If your pet ate a lot, or you are worried, call your vet. Say what was eaten, how much and when, and have your pet's weight ready.

For the children

"A grown-up can give cats a little cucumber now and then. Their own food is still their dinner."

A job: Be the label reader. Before a grown-up shares any food with the cat, check this page, and ask a grown-up if the food is not on it.
