We avoid cat products that contain corn and other food products that are high in Lectins. It could cause increase in allergy symptoms and is not good to eat in high amounts for humans or animals. Many brands use proteins or grains which is high in lectins to supplement healthy based protein and grains.
Recommended Diet
Disclosure I am not veterinary or a nutritionist for cats. I am just recommending based on research and experience.
This fish oil brand is best for their health and heart. It can decrease the chances of other illnesses like HCM.
Give 2 capsules per a cat. Increase on dosage depending on results. Should see their fur feeling silky soft and not dry.
We use the Whole Paws brand for can food. We do not recommend their dry food, since it contains lectins. Lectins will prevent absorption of nutrients. It has more bigger effects on sensitive pets, like Ragdolls and other purebreds, so we do not recommend foods that contain lectins. It will also harm mix breeds cats health, if their body is less fit. Since you can never know if your cat is one of those well fit cats, it's best to avoid it to begin with. My husbands orange brown cat ended up getting a swelled stomach due to a high lectin cat food brand. While his other cat on the same diet didn't. But over long time, it has affected the other cats health. Swelled stomachs are usually caused by lack of nutrition. The swelled stomach went away after removing lectins in his cats diet.
Raw Diet
If you were to feed your cat the raw diet, you would need to freeze the meat first if gotten fresh from the butcher, like with salmon to remove possible parasites. When you feed your pet a raw diet, you need to feed liver, heart and other organ meat. Not just raw ground meat or chicken breast. Because if you go with the natural raw meat diet, then you need to mimic what your pet would be eating if they were in the wild. Since they are not eating vegetables, they get all their vitamins and other needed nutrients like minerals from other parts of the animal. Which is the organ meat.
Personally I find feeding pets raw meat very risky. Somehow other people are able to manage feeding their pets raw meat and they are very healthy. But it just takes one bad egg to get salmonella poisoning. I eat raw eggs and raw foods all the time. The issue is I know I caught it, if I caught it and can cure it by taking activated charcoal. As for my pets, I don't know if they caught or how to take care of it. So I'd rather avoid that risk.
