2) Viscera (such as chicken liver): The liver contains a lot of vitamin A. Excessive intake of vitamin A will lead to muscle stiffness, neck pain, bone and joint deformation and liver diseases. Therefore, even if cats like to eat liver again, they can't eat it often. Just order a hearty meal every once in a while.
Raw fish/meat/raw eggs: eating raw food for a long time can easily lead to insufficient intake of some vitamins or minerals, and it is easy to be infected with parasites and bacteria.
3) Chocolate: Theobromine contained in chocolate can cause food poisoning, and cats may suffer from diabetes if they eat too many sweets such as chocolate and candy.
4) Milk: For cats, the nutrition of milk is not comprehensive, and it is definitely impossible to make up for it in quantity. On the contrary, if you drink too much milk, cats will have diarrhea because they can't decompose it. 5) Fish bones/chicken bones: The bones are hard and easy to scratch the cat's throat and esophagus.
6) Dog food: Dogs are omnivores and cats are carnivores, and their nutritional needs are still very different.
