Can Cats Eat Kale?
Yes, with caution. Plain kale is not considered highly toxic to cats, but it is not an ideal food for obligate carnivores and too much may cause stomach upset or be a concern for cats prone to calcium oxalate urinary stones.
Kale is usually safe only in tiny amounts
A small bite of plain kale is unlikely to harm most cats, but kale should only be an occasional treat. Cats are obligate carnivores, and kale may cause gastrointestinal upset; frequent or larger amounts may be a poor choice for cats with a history of calcium oxalate urinary stones or urinary disease.
How urgent is this?
Go to the ER now
- ● Your cat is having trouble breathing, has severe facial swelling, collapses, or cannot keep water down after eating kale
- ● Your cat has a known urinary blockage history and now strains to urinate, cries in the litter box, or produces little to no urine
See a vet within 24 hours
- ● Your cat ate a large amount of kale and now has repeated vomiting or diarrhea
- ● Kale was prepared with garlic, onion, chives, heavy salt, butter, oils, spicy seasoning, or other ingredients that may be toxic or irritating to cats
- ● Your cat seems painful, lethargic, refuses food, or is drooling excessively after eating kale
- ● Your cat has kidney disease, a history of bladder stones, or another chronic illness and ate more than a small nibble
Watch at home, call if it worsens
- ● Your cat ate a small amount of plain kale and is acting normal
- ● Mild temporary stomach upset after a tiny bite
- ● Your cat licked or nibbled a little cooked, unseasoned kale
How to Safely Feed Kale to Your Cat
If you offer kale at all, keep it rare and very small. Cats do not need vegetables for balanced nutrition, so kale should never replace a complete cat food.
- Offer only a tiny amount, such as a small shred or bite-sized piece
- Serve plain and cooked or finely chopped to improve digestibility
- Do not add garlic, onion, salt, sauces, dressings, or seasoning
- Avoid kale chips and smoothies because they often contain salt, oils, or other unsafe ingredients
- Skip kale entirely for cats with a history of calcium oxalate stones, urinary issues, or sensitive stomachs unless your veterinarian says otherwise
