What Vitamins Do Cats Need?

Cats are complex creatures that require a well-balanced diet to maintain their health and happiness. While most of their nutritional needs can be met through a high-quality cat food, there are certain vitamins that cats need to stay healthy. In this article, we’ll explore the vitamins that cats need and why they’re important.

Vitamin A

Vitamin A is an essential nutrient that is important for maintaining healthy skin, coat, and eyesight. Cats that are deficient in vitamin A may experience dry, flaky skin, poor vision, and even blindness. Vitamin A can be found in liver, egg yolks, and fish oils. However, it’s important to note that too much vitamin A can be toxic to cats, so it’s important to consult with your veterinarian before supplementing your cat’s diet with this nutrient.

Vitamin B1 is important for maintaining a healthy nervous system in cats. Without enough vitamin B1, cats may experience neurological problems, including seizures. Vitamin B1 can be found in pork, liver, and whole grains.
