Why?
Lentils are legumes full of starch and fiber that ferment in the gut and cause gas and bloating. Raw or undercooked, they contain lectins and other compounds that irritate the digestive tract; thorough cooking neutralizes most of them. Their plant protein doesn't replace meat for an obligate carnivore.
How much?
A teaspoon of well-cooked lentils, boiled without salt and mashed, once in a while. Rinse canned lentils well, since they're often salted.
The risks
- Gas, bloating, tummy discomfort
- Raw or undercooked lentils: digestive irritation
- Dishes cooked with onion, garlic, bacon or sausage
- Salt in canned lentils
Your cat ate some: what now?
A few plain lentils aren't a problem; at worst, some gas. If your cat ate a seasoned lentil dish, watch for vomiting, diarrhea or lethargy over 24 to 48 hours. Call your vet if it contained onion or garlic.
Better options
If you want to give a vegetable, plain cooked peas or green beans go down more easily. For protein, a piece of cooked meat is still the gold standard.
Common questions
Can cats eat canned lentils?
They're already cooked but often salted, so rinse them well under running water. Skip any that are seasoned or packed with onion or bacon.
Can cats eat lentil soup?
No. Lentil soup and dal almost always contain onion, garlic and spices. Onion and garlic are toxic to cats, even cooked.
This information is general and does not replace advice from a veterinarian. If your cat has swallowed something toxic, call your vet or an animal poison control center right away, without waiting for symptoms.
