Cat Nutrition vs. Cat Supplements: What Cat Parents Need To Know

In the age of wellness trends and fad diets, it may be tempting to lean on a sprinkling of supplements to ensure your cat is healthy. But when it comes to the health of your furry friend, shortcuts don't cut it, and supplements aren't going to fix a poor meal plan.

Cats are obligate carnivores with specific dietary needs, and good cat nutrition starts with a complete and balanced food that's made just for them. While cat supplements may be recommended by your veterinarian to address specific concerns, they are not a replacement for feeding your furry friend food that is complete and balanced.

In this guide, you'll learn how to build a strong nutritional foundation for your cat, which vitamins matter, when supplements make sense, what types exist and how to work with your vet to choose the best nutrition for your cat.

A complete and balanced cat food contains all the vitamins and minerals your furry friend needs. This includes fat-soluble vitamins (A, D, E, K), B vitamins and key minerals to keep their vision sharp, immune system strong, coat shiny and bones solid:

• Vitamin A: Important for vision, skin and immune support

• Vitamin D: Critical for normal calcium-phosphorus balance and bone health

• Vitamin E: Helps protect cells and supports the immune system, skin and muscles

• B-complex (thiamine, niacin, B12, etc.): Crucial for a healthy metabolism, nerves and red blood cells

Cats' bodies can’t make these vitamins on their own, so they must get them from their food source. But remember: If your cat is eating a complete and balanced food, they're already set — extra supplements and minerals should only come in if your vet recommends them.

Supplements can come in several forms, including chews, liquids, capsules or powders. Here are some common cat supplements you'll see and when they might be considered (always under veterinary guidance):

• Essential Fatty Acids (Omega-3s): These come from fish oil and provide skin and coat support, healthy brain aging support and joint health support.

• Joint Supplements: In addition to omega-3s, joint supplements commonly include glucosamine and chondroitin.

• Probiotics, Prebiotics and Postbiotics: Biotics may be recommended for specific digestive concerns under veterinary direction.

• Anti-Anxiety Supplements: Calming supplements, such as L-theanine, can decrease anxiety and related litter box problems in some cats.

• SAMe: This supplement — made from the amino acid methionine and primarily used for liver health and function — can also support aging feline brains, particularly in older cats that are showing signs of dementia.10

Vitamin blends or multivitamins are usually unnecessary if you're feeding your cat a complete and balanced food. Deficiencies or special conditions should be diagnosed and supplemented under veterinary supervision only.

Quick Supplementing Tips

A couple of simple rules can help keep supplement use safe and effective:

• Avoid giving your cat any supplement made for people. Human products often contain additives that aren't safe for cats, and it's nearly impossible to administer correctly.11

• Skip any supplement that claims to replace a cat's complete and balanced meal plan. Food should always come first, and supplements are only there to fill a gap under the direction of your vet.

If you're not sure, ask your vet. They can help you determine which supplements, if any, may benefit your cat.

Cat supplements can help in specific, vet-guided scenarios, but they don't replace the daily foundation of a complete and balanced cat food. Feed for the life stage, cover cat vitamins and minerals through complete and balanced food and partner with your vet to decide if any cat nutritional supplement belongs in your pet’s health plan.
