Can Cats Eat Cheese?

Rare Treat

Not needed in a cat's diet: a complete and balanced cat food provides what a cat needs (VCA).

Portion:Within the 10% treat limit (VCA); no per-food amount is published

Frequency:Rare treat

Warning: Most cats are lactose intolerant (VCA), so dairy can cause digestive upset.

This is general information from the sources listed below, not veterinary advice. For your pet's diet, health conditions or any reaction after eating, contact a licensed veterinarian.

The Full Picture

Why Rare Treat?

Most adult cats lose much of the lactase enzyme needed to digest lactose after weaning, so dairy can cause gas, vomiting, or diarrhea. Harder, aged cheeses such as cheddar, Swiss, and Parmesan are lower in lactose than soft cheeses like mozzarella, which makes them a comparatively better option in small amounts.

Preparation

How to Serve It Safely

Stick to small amounts of hard, aged, plain cheese. Avoid moldy or blue-veined cheeses entirely — the Penicillium mold used to make them can be toxic to cats.

FAQ

Common Questions

Is all cheese equally risky for cats?

No. Hard, aged cheeses like cheddar or Parmesan are lower in lactose and generally better tolerated than soft cheeses, and moldy cheeses like blue cheese carry a separate toxicity risk from the Penicillium mold.

Which cheeses are the least risky for cats?

Hard, aged cheeses are lower in lactose than soft cheeses, so a pea-sized piece is the least likely to upset the stomach. Cheese is still high in fat and salt, so it is only an occasional treat.
