Cheese

Caution

Verdict

Small amounts OK for some cats — high in fat and lactose.

Toxic principle: lactose, high fat
Source: ASPCA

Verdict

Cheese is high in fat and lactose, which can cause GI upset in lactose-intolerant cats (most adult cats). Small amounts of plain, mild cheese may be tolerated by some cats as an occasional treat, but it should not be a regular part of their diet. Avoid blue cheeses (toxic), onion/garlic-flavored cheeses, and processed cheeses with high sodium.

Symptoms to watch for

  • diarrhea
  • vomiting (if lactose intolerant or overfed)
  • pancreatitis symptoms with large fatty servings

What to do

Keep portions tiny — a pea-sized piece as an occasional treat. If your cat has a history of digestive sensitivity, avoid cheese entirely. Never feed blue, Roquefort, or seasoned cheeses.
