Can dogs and cats eat grass?

CarefulMost pets eat some grass; it is normal unless it is treated or they vomit a lot.
Avoid lawns treated with fertilizer, weed killer or slug pellets. Cat grass (oat or wheat grass) is a safe indoor version.
What to watch for
Vomiting now and then is normal; repeated vomiting or treated lawns: call the vet.
If they ate it
Offer water, skip the next meal, and call your vet if vomiting or diarrhea lasts more than a day or your pet seems unwell.
Careful for dogs means: fine in a small amount, prepared as described, and not for every pet; the details say when to skip it.
