Siamese cats were common throughout Thailand (formerly Siam) for centuries, but it took some time for their unusual appearance to catch on. Once it did, these cats quickly became fashionable and, by the 19th century, the Siamese had become one of the most popular breeds of cats throughout Europe and North America.
With blue almond shaped eyes, large ears, and pointed coloration, this breed is easily recognizable. Early examples of the breed were only shown with seal points (a dark brownish black color), but blue, chocolate, and lilac points were soon to follow. Today, the Siamese comes in a wide variety of points and patterns including tabby points.
In addition to its unusual appearance, the Siamese cat breed is known for its active and playful nature. These frisky felines are full of energy, and they require a nutritious diet to meet their needs.
Best Cat Food for Siamese Cats Reviewed
Like all cats, Siamese cats are obligate carnivores and thus have a biological requirement for a meat-based diet. The best cat food for Siamese cats is packed with animal protein and healthy fats with little to no carbohydrate. Whether fresh, raw, homemade, canned, or kibble, a high-quality cat food for Siamese cats is nutritionally balanced and formulated to meet these basic needs.
#1 Overall Best: Open Farm Wild-Caught Salmon Dry Food
- Made In: United States
- Guaranteed Protein: 37% Min
- Age Range: Adult
- Calories Per Pound: 1789
- Typical Cost Per Day: $0.74 per day
Provide your cat with high-quality animal protein and healthy animal-based fats with this wild-caught salmon formula from Open Farm. It features wild Pacific salmon as the main ingredient, supplemented with both ocean whitefish meal and ocean herring meal.
In addition to being packed with species-appropriate animal protein, this recipe contains herring oil and salmon oil as natural sources of omega-3 fatty acids which help support your Siamese cat’s skin and coat. We’d prefer to see them listed before the coconut oil, but we’re happy to see them on the list.
Though this recipe is rich in animal protein and healthy fats, it is higher in fiber and carbohydrate content than we’d like. The overall quality of the recipe is high, especially considering the ingredients are 100% human-grade and ethically sourced, but we could do without some of the plant-based ingredients – particularly the legumes and pulses.
Ingredients
Wild Pacific Salmon, Ocean Whitefish Meal, Ocean Herring Meal, Garbanzo Beans (Chickpeas), Red Lentils, Coconut Oil (preserved with mixed tocopherols), Herring Oil (preserved with mixed tocopherols), Pumpkin, Natural Flavor, Green Lentils, Salmon Oil, Non-GMO Cranberries, Chicory Root, Apples, Dandelion Greens, Choline Chloride, Salt, Turmeric, Dried Yucca Schidigera Extract, Mixed Tocopherols (a natural preservative), Calcium Carbonate, Zinc Proteinate, Iron Proteinate, Copper Proteinate, Manganese Proteinate, Sodium Selenite, Calcium Iodate, Vitamin E Supplement, Thiamine Mononitrate, Niacin Supplement, D-Calcium Pantothenate, Biotin, Vitamin A Acetate, Riboflavin Supplement, Vitamin B12 Supplement, Vitamin D3 Supplement, Folic Acid, Taurine, Rosemary Extract

Unless you cancel, the subscription will roll over into a monthly plan catered to your cat’s protein preferences and calorie needs.
The first ingredient in this Ground Bird fresh cat food formula is chicken muscle meat. Chicken liver provides additional protein while cod liver oil serves as the only source of added fat. The food contains about 48% protein and over 31% fat, both measured as dry matter. It’s an easily digestible recipe with a minced mouthfeel and it’s rich in hydrating moisture.
At 40 calories per ounce, this chicken recipe is fairly energy-dense. For very young or active Siamese cats who need a higher concentration of calories, the beef-based Smooth Cow formula may be a better choice at 49 calories per ounce.

#3 Premium Pick: The Honest Kitchen Grain-Free Turkey Recipe Dehydrated Cat Food
- Made In: United States
- Guaranteed Protein: 35% Min
- Age Range: Adult
- Calories Per Ounce: 13
- Typical Cost Per Day: $1.24 per day
Grace by The Honest Kitchen contains 70% cage-free turkey, making it a nourishing high quality protein choice for your meat-loving cat. This is a dehydrated food, so you’ll need to mix in warm water and let it sit for a few minutes before serving it. Once rehydrated, it is a rich source of moisture.
The first ingredient in this formula is turkey, supplemented with additional protein from eggs. The other main ingredients are whole-food sources of essential nutrients like dehydrated pumpkin, parsley, kale, and cranberries. We’d prefer to see fewer plant ingredients on the whole, however, – especially starchy ones like potatoes – and the carbohydrate content of this formula is fairly high.
Ingredients
Dehydrated Turkey, Dehydrated Eggs, Dehydrated Pumpkin, Dehydrated Potatoes, Dried Parsley, Dehydrated Kale, Dried Cranberries, Minerals [Tricalcium Phosphate, Potassium Chloride, Choline Chloride, Zinc Amino Acid Chelate, Iron Amino Acid Chelate, Potassium Iodide, Copper Amino Acid Chelate, Sodium Selenite], Taurine, Vitamins [Vitamin E Supplement, Vitamin B12 Supplement, Thiamine Mononitrate (Vitamin B1), D- Calcium Pantothenate (Vitamin B5), Riboflavin (Vitamin B2), Vitamin D3 Supplement].

While the sole source of added fat is vaguely-named vegetable oil, there are no major red-flag ingredients. This recipe is free from fillers and by-products as well as artificial additives.

#5 Best Dry Food: Wysong Optimal Vitality Adult Feline Formula Dry Cat Food
- Made In: United States
- Guaranteed Protein: 50% Min
- Age Range: Adult
- Calories Per Pound: 1721
- Typical Cost Per Day: $0.55 per day
Crafted by veterinarians, this Optimal Vitality formula from Wysong is a quality choice in dry food for cats. Packed with animal-based protein from concentrated sources like chicken meal and turkey meal, this recipe also contains a rich balance of omega-3 and omega-6 fatty acids.
In addition to being rich in protein and healthy fats, this formula is supplemented with fiber and probiotics to support healthy digestion. An array of nutraceuticals helps support other aspects of your Siamese cat’s health as well, all in a low-glycemic formula ideal for weight control and diabetic cats.
The downside of this formula is the rather high carbohydrate content. In addition to plant ingredients like peas and flaxseeds, we see several concentrated plant proteins like pea protein and potato protein. As a dry food, this formula also lacks the moisture your cat needs for optimal hydration.
Ingredients
Chicken Meal, Organic Chicken, Turkey Meal, Pea Protein, Potato Protein, Peas, Chicken Fat (preserved with Mixed Tocopherols), Flaxseeds, Dried Plain Beet Pulp, Natural Flavor, Sesame Seeds, Montmorillonite Clay, Crab Meal, Dried Whey, Coconut Oil, Chia Seeds, Salt, Taurine, Calcium Carbonate, Calcium Propionate (a preservative), Dried Tomato Pomace, Choline Chloride, Yeast Extract, Organic Barley Grass Powder, Dried Blueberry Powder, Dried Yogurt, Dried Kelp, Apple Pectin, Dried Kale, Dried Spinach, Dried Carrots, Fish Oil, Citric Acid (a preservative), Inulin, Mixed Tocopherols (a preservative), Rosemary Extract, Yeast Culture, Minerals (Potassium Chloride, Zinc Proteinate, Zinc Sulfate, Ferrous Sulfate, Iron Proteinate, Copper Sulfate, Copper Proteinate, Manganese Sulfate, Manganese Proteinate, Sodium Selenite, Calcium Iodate), Vitamins (Ascorbic Acid [source of Vitamin C], Vitamin E Supplement, Niacin Supplement, Calcium Pantothenate, Vitamin A Supplement, Thiamine Mononitrate, Pyridoxine Hydrochloride, Riboflavin Supplement, Vitamin D3 Supplement, Biotin, Vitamin B12 Supplement, Folic Acid), Dried Aspergillus Oryzae Fermentation Product, Dried Enterococcus Faecium Fermentation Product, Dried Lactobacillus Casei Fermentation Product, Dried Lactobacillus acidophilus Fermentation Product, Dried Bacillus Subtilis Fermentation Product, Dried Lactobacillus Plantarum Fermentation Product, Dried Lactobacillus Lactis Fermentation Product, Pepper.

#6 Best For Kittens: Wellness Complete Health Chicken Entrée Pate Canned Kitten Food
- Made In: United States
- Guaranteed Protein: 11% Min
- Age Range: Kitten
- Calories Per Ounce: 66
- Typical Cost Per Day: $2.83 per day
All cats require balanced nutrition, but it’s especially important for your Siamese kitten to get the right balance of nutrients in early life. Protein is essential and this Wellness Complete Health formula has plenty of it. Fresh chicken and chicken liver provide all the animal-based protein your kitten needs.
In addition to protein, this formula is rich in healthy animal-based fats like chicken liver and menhaden fish oil. Menhaden fish oil is particularly high in DHA which helps promote healthy brain and eye development in kittens. Plus, this food is exceptionally calorie-dense, with 122 calories in every 3 oz can. This is important to fuel your kitten’s rapid growth.
On the downside, this formula contains several plant ingredients, and the overall carbohydrate content is a little higher than we’d like. That being said, it’s a decent recipe that offers good palatability and high digestibility for kittens.
Ingredients
Chicken, Chicken Liver, Chicken Broth, Carrots, Natural Flavor, Cranberries, Guar Gum, Ground Flaxseed, Potassium Chloride, Taurine, Salt, Menhaden Fish Oil (preserved with Mixed Tocopherols), Choline Chloride, Magnesium Sulfate, Cassia Gum, Xanthan Gum, Iron Proteinate, Zinc Proteinate, Beta-Carotene, Vitamin E Supplement, Thiamine Mononitrate, Copper Proteinate, Manganese Proteinate, Sodium Selenite, Niacin, d-Calcium Pantothenate, Pyridoxine Hydrochloride, Riboflavin Supplement, Vitamin A Supplement, Biotin, Potassium Iodide, Vitamin D3 Supplement, Vitamin B12 Supplement, Folic Acid, Rosemary Extract.

- Made In: New Zealand
- Guaranteed Protein: 9.1% Min
- Age Range: Adult
- Calories Per Ounce: 27
- Typical Cost Per Day: $5.63 per day
As your Siamese cat gets older, his basic nutritional needs will change a little bit. Many senior cats have trouble keeping on weight particularly if they have a condition such as chronic kidney disease, so it’s particularly important to provide a protein- and calorie-dense diet. This beef and hoki recipe from Feline Natural is a great option.
With the top five ingredients being animal-based sources of protein, this recipe is very species-appropriate for your Siamese cat. Not only do we see fresh proteins like hoki and beef, but you get those nutrient-rich organ meats as well – this recipe even contains beef blood.
With its limited list of ingredients, this recipe is highly digestible, and it is rich in the moisture your cat needs for optimal hydration. Plus, the soft texture is easy for older cats to eat. There are a few plant ingredients, but the overall carbohydrate content is still very low.
Ingredients
Beef Heart, Hoki, Beef, Beef Kidney, Beef Liver, Beef Blood, Sunflower Oil, Flaxseed Flakes, New Zealand Green Mussel, Dried Kelp, Taurine, Vitamin E Supplement, Magnesium Oxide, Zinc Proteinate, Copper Proteinate, Manganese Proteinate, Thiamine Mononitrate, Vitamin D3 Supplement, Folic Acid, Water added for processing.

Common Breed Health Issues
A healthy diet is the best way to prevent chronic health problems in cats, but there are some things that just can’t be avoided. Certain breeds are prone to common health issues, and it’s important to understand the potential problems lurking in your Siamese cat’s future so you can protect him.
Some of the most common health problems seen in the Siamese cat breed are amyloidosis, asthma, certain types of cancer (e.g. mediastinal lymphoma) and hip dysplasia. This breed is also prone to eye problems like progressive retinal atrophy (PRA) and poor night vision. Early Siamese cats were often cross-eyed, but this trait is far less common today thanks to selective breeding.
Some Siamese cats are also prone to sensitive tummies (particularly vomiting) and could require a sensitive diet. Ensuring that your Siamese is on a high quality diet could prevent tummy upsets. Avoid treats and humans food (e.g. milk, fatty meat) as much as possible.
Siamese cats are also known to eat strange objects, this is called Pica. Pica is the ingestion of inedible objects such as wool, plastic and other items. The reason for this is unknown but it’s advisable to keep inedible items away from your Siamese cats wherever possible.
Many cats are at risk of obesity and the Siamese cat is no different. . The Siamese is a small-medium cat, typically weighing 8-15 pounds depending on the gender.

Obesity is typically the result of numerous factors including overeating and lack of exercise. Feeding your Siamese a species-appropriate diet and following the feeding recommendations is essential, though you should keep an eye on your cat’s body condition and adjust his daily portion as necessary.
If you want to have complete control over your cat’s diet, consider a raw or homemade cat food diet. It may cost a little more in some cases, but you don’t have to worry about fillers or artificial additives, plus you can customize your cat’s diet according to his preferences. Just be sure to use a nutritionally balanced recipe and to check with your veterinarian first, particularly if your Siamese has any health conditions
Final Thoughts
As you can see, there are some great options out there for your Siamese cat’s diet. It’s up to you to decide what you buy according to your budget and personal preferences, but don’t forget your number-one priority: your Siamese cat’s health and wellness.
It’s well worth spending a few extra dollars a month to upgrade your cat to a better diet, especially when it comes to preventing long-term health problems. Even if you can’t afford more than middle-shelf cat food for your Siamese’s daily diet, keep an eye out for sales on higher quality products you can use to supplement your cat’s diet from time to time.

Now I’m even more confused, my siamese cat seems to have a tender stomach and he has been eating Fancy Feast but he does not like tie chicken but the ingredients list chicken broth only and way down the list chicken liver, he is not getting much chicken should I try cooking some chicken for him? For a senior Siamese cat what do you honestly recommend? He is 13 yrs old and I want him around for a while longer he is wonderful. He had a spell with diarrhea
and he is over that but sometimes brings up a little liquid. Can you help me?
Thank you
Norah
Hi Norah,
For senior cats, I highly recommend reading our article about Best Cat Food for Senior Cats
You can try cooking chicken, I recommend reading Making Cat Food: Homemade and Raw Cat Food Diets an excellent article written by Mallory Crusta
Each cat is different so there is not a “one size fits all” recommendation we can give you.
Best thing to do is to consult you vet as he/she can provide personalized suggestions relevant to your cat’s unique situation.
Hope this helps.
Purrs,
Pedro
Hi I have a 8 year old Siamese cat and every once in a while I notice a streak of blood in his stools. Doesnt seem to be to bothered by it. still eating and acting like his normal self. I did just today try switching him to more of a wet food but still kept a little bit of the dry food in there and he had more of a putty like stool with a little blood..Do you think he just has a sensitive stomach or should I be concerned?
Hello Lindsey, thanks for commenting! There are a lot of factors to consider here—like the color of your cat’s stool, the color of the blood, and any other underlying conditions. I would recommend seeing a vet, but in the meantime, you might appreciate our article on the meaning of blood in a cat’s stool: https://cats.com/blood-in-cat-stool
Hello, I currently have a 3 month old (i think) girl names Katya.
It seems that taking care of my child will be more complicated than i thought, i am currently feeding her blue buffalo pate (she doesn’t like it that much) mixed with dry food (i believe it was a wellness brand product.)
I am somewhat lost because at this point I can tell that she LOVES stuff with gravy and texture but a lot of those products seem to have ingredients that are possibly linked to future stomach issues and i think i am supposed to avoid them. Any advice?
Hello George, thanks for your comment! There are a few thickener-free but richly-textured, gravy-inclusive wet foods on the market—you’ll find some of them on our list of the best wet foods you can buy.

Hi Natasha, thank you for commenting! It sounds like your cat has some digestive issues, so I would concentrate on that more than her breed when trying to find an appropriate food. With that in mind, you might like our article on the best cat food for sensitive stomachs: https://cats.com/best-cat-food-for-sensitive-stomach
Other than that, you might want to talk to a veterinarian to determine why your cat vomits and has trouble going number two. Hope this helps!

I am surprised that you recommend a brand of fancy Feast w/ one of the main igrediants being wheat gluten which is NOT good for cats. We carefully check to make sure this is NOT in our Obilage carnivores food. It’s a cheap subtistute for the meat they need. Fancy Feast used to be better until it was sold to netsle . I have always seen nitrates in the salmon, but their other foods used to be good. Please do not recommend unsitable foods for cats, because some may not be aware. I’ve had to deal w/ illnesses from bad (dry) food.
Thank you!
Um… I am wondering where you base the Siames cats weight between 6-10 Lbs??? I have had 5 Siamese cats and the Males are generally quite a bit heavier then 1p lbs with most averaging between 14-18 lbs… They are long cats and far from overweight.
Hi Kevin, there is a bit of variation from cat to cat even within the breed, but I’ve found that the average male Siamese will weigh between 11 to 15 pounds, while females weigh 8 to 12 lbs. I will update this article accordingly, as it seems the information presented here represents only the lower end of the average weight spectrum.
