Can Cats Eat Cheese?

Yes, with caution — a small amount of plain cheese is not usually toxic to cats, but many adult cats are lactose intolerant and can develop vomiting, diarrhea, gas, or abdominal discomfort after dairy.

Cheese is not toxic to cats, but it is not an ideal treat

Most cats can eat a very small amount of plain cheese without poisoning, but cheese can cause digestive upset because many adult cats do not digest lactose well. Avoid large portions, rich cheeses, and any cheese flavored with garlic, onion, chives, or other seasonings.

How urgent is this?

Emergency

Go to the ER now

  • ● Your cat ate cheese containing onion, garlic, chives, or other toxic ingredients and is now weak, vomiting repeatedly, or having trouble breathing
  • ● Your cat is having facial swelling, collapse, or severe breathing difficulty after eating cheese
  • ● Your cat ate moldy or blue cheese and develops tremors, twitching, seizures, or severe agitation
Urgent

See a vet within 24 hours

  • ● Your cat ate a large amount of cheese and now has repeated vomiting, significant diarrhea, marked lethargy, or abdominal pain
  • ● Your cat has a history of pancreatitis or other digestive disease and becomes ill after eating cheese
  • ● Your kitten, senior cat, or medically fragile cat ate cheese and is showing any digestive upset
Monitor

Watch at home, call if it worsens

  • ● Your cat ate a tiny amount of plain cheese and is acting normal
  • ● Mild gas or one soft stool after a small dairy exposure
  • ● Cheese was used in a very small amount to hide a pill and no symptoms developed

How to Safely Feed Cheese to Your Cat

Cheese should only be an occasional treat for cats, not a regular part of the diet. Because cats are obligate carnivores and many adults are lactose intolerant, keep portions very small and choose the plainest option possible.

  • Offer only a tiny bite of plain cheese, not a full slice or large cube
  • Choose plain, unseasoned cheese with no garlic, onion, chives, pepper, or spicy add-ins
  • Skip cheese if your cat has had vomiting, diarrhea, or gas after dairy before
  • Avoid high-fat, heavily processed, or very salty cheeses
  • If your cat develops digestive upset after cheese, stop feeding it and call your vet if symptoms persist

Common Questions

Is cheese toxic to cats?
Cheese itself is not considered toxic to cats, but it is also not an especially appropriate food for them. Many adult cats are lactose intolerant, so cheese can cause diarrhea, vomiting, bloating, or abdominal discomfort even when it is not poisonous.
Why can cheese upset a cat's stomach?
Most cats lose much of their ability to digest lactose after kittenhood. That means dairy products, including cheese, may lead to intestinal upset. Rich or fatty cheeses can also be harder on the digestive system.
How much cheese can a cat have?
If your veterinarian says cheese is okay for your cat, keep it to a tiny bite only as an occasional treat. Treats should make up no more than 10 to 15 percent of daily calories, and many cats do best with even less dairy than that.
Are some cheeses more dangerous than others for cats?
Yes. Avoid cheese with garlic, onion, chives, or other flavorings, because those ingredients are toxic to cats. Blue or mold-ripened cheeses are also best avoided, especially if your cat eats more than a trace amount or shows neurologic signs like tremors.
Is cheese different for cats than for dogs?
Both cats and dogs can get digestive upset from cheese, but cats are obligate carnivores and dairy is generally less appropriate for their routine diet. Cats are also more sensitive than dogs to certain added ingredients commonly mixed into human foods, especially onion and garlic, so flavored cheeses can be a bigger concern.
