Vitamin A is very important for both humans and cats. It can be found mainly in liver, fish liver oil, milk, and egg yolks, and helps maintain your cat’s skin, coat, muscles, nervous system, and thyroid function. A deficiency could lead to stunted growth in kittens, muscle weakness, a scruffy coat, and night blindness. An overdose of vitamin A, on the other hand, is possible but super rare as it’s nearly always caused by cat parents feeding their feline vitamin A supplements or excessive amounts of liver. To make sure your cat gets just the right amount of vitamin A, choose high-quality cat food.
There are 8 different types of vitamin B: thiamin (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folic acid (B9), and cobalamin (B12). The thing is, vitamin B is water soluble – which means any vitamin B your cat’s body doesn’t need at that moment is eliminated through their urine instead of being stored. As a result, these nutrients need to be provided to your feline on a daily basis, through a complete and balanced diet. Vitamin B deficiencies are however very rare, though they can occur when cats are anorexic or eat copious amounts of seafood.
Couldn’t find any mention of vitamin C when studying the packaging of your cat’s food? Don’t worry – unlike humans, cats can produce their own vitamin C by breaking down glucose. Make sure you feed your cat a complete diet though, to make sure they won’t lack any nutrients.
While humans can get their daily dose of vitamin D through the sunlight on their skin, cats can’t. Cats need this vitamin to be supplied to them in exactly the right amount, which is why it’s so important to offer your cat a complete and balanced food. Too little vitamin D can lead to heart disease and bone disorders, though too much of this vitamin can be problematic as well.
Vitamin E is an essential vitamin for cats, which means your feline cannot create it inside their body by combining other nutrients, so vitamin E must be part of their daily diet. As vitamin E is an antioxidant, it plays an important role in protecting your cat against heart disease, vision loss and neurological problems. A complete and balanced diet is vital to prevent vitamin E deficiency, as it can be caused by a diet containing too many polyunsaturated fatty acids.
Vitamin K can mainly be found in leafy greens and other vegetables like broccoli and Brussels sprouts. You will notice that these veggies aren’t usually present in a cat’s diet, but that’s no problem at all. Cats can synthesize their own vitamin K, so only the building blocks of this vitamin need to be present in their food.
