Siameses are carnivores. Never forget that when you’re trying to decide which food your Siamese should eat. If you don’t stick to his intended diet, your Siamese will become a picky eater. You will have a difficult time getting your Siamese to eat if you’re giving him food that is not meat or formulated from meat products.
What you should feed your new Siamese.
You mustn’t forget that Siameses share a recent common ancestor with the largest of felines — tigers, lions,and cheetahs, etc. — so take that to heart when feeding your Siamese. You won’t ever see a full grown cougar on Animal Planet drinking milk, chewing grass, or eating an apple in his natural habitat.
