Cat Grass
SafeVerdict
Yes — safe and often beneficial. Occasional vomiting after eating it is normal.
Verdict
Cat grass (usually wheat, oat, barley, or rye grass sold specifically for cats) is not on the ASPCA's toxic plant list and is not toxic. Many cats graze on it instinctively, and it can add fiber to the diet and may help move swallowed hair through the digestive tract. This is different from lawn or garden grass, which can be treated with pesticides, herbicides, or fertilizer — those chemicals are the real danger, not the grass itself. Only offer grass grown specifically as a pesticide-free cat grass product.
Symptoms to watch for
- • mild vomiting shortly after eating (a normal grazing behavior, not a sign of poisoning)
- • loose stool with very large amounts
What to do
No treatment needed for grazing on genuine, pesticide-free cat grass. If a cat has eaten lawn or garden grass that may have been treated with chemicals, treat it as a possible chemical exposure and contact a vet.
