Why
Complete cat food is exactly right for a cat. Match the life stage and follow the feeding guide; wet food also helps a cat's water intake.
Signs to watch for if your cat has eaten cat food
Vomiting
Diarrhea or loose stools
Loss of appetite
Belly discomfort or unusual tiredness
Signs vary with the amount and with the individual pet, and some appear only after a day or more. Their absence does not mean your cat is in the clear — call rather than watch.
What to do now
Serve it plain, in small pieces, as an occasional treat. Keep all treats to under about a tenth of daily calories, and introduce anything new in a small amount so you can spot a sensitive stomach.
Never induce vomiting and never give any medicine unless a vet tells you to. With some substances it causes more damage than the poison. This page tells you when to get help — it never tells you how to treat at home.
Safer treats made for cats
If you're sharing food because you want to treat them, a treat formulated for cats does the job without the guesswork.
Verdicts are transcribed from the cited veterinary sources, never inferred. Where a source establishes a finding for one species only, the other species is left null and the page says to ask your vet — a dog finding is never copied onto a cat.
