The short answer

Yes. Cucumber is non-toxic to cats and is about 95% water, so a small peeled slice is a refreshing, almost calorie-free nibble. Cut it small and serve it plain. Pickles are a different story: they're high in salt and often flavoured with garlic and dill.

Why the verdict

Cucumber contains water, a little fibre and trace nutrients, and nothing known to be toxic to cats. Too much can loosen stools. Pickled cucumbers are soaked in brine, which is high in sodium, and often contain garlic.

How to prepare it

  • Wash; peeling is optional but easier on the stomach.
  • Slice thinly and cut into small pieces.
  • No pickles, dressing or salt.
Kittens: A small piece is fine.

Signs of trouble

  • Loose stool
  • Vomiting (rare)
When to call the vet: If vomiting or diarrhoea lasts more than 24 hours, or your cat is lethargic, stops eating or seems in pain. ASPCA Poison Control: (888) 426-4435.
