Lentils

Lens culinaris
Also known as:lentils
CatCaution

**Cats are obligate carnivores, so legumes serve no nutritional purpose for them**; **raw lentils hold lectins that cause vomiting and diarrhoea**, and their fibre promotes gas, so keep lentils to a rare small amount cooked soft and mashed into wet food.

DogSafe

Cooked-soft lentils bring plant protein and dietary fibre at a moderate calorie cost, so crushed or pureed plain lentils work as an occasional treat or a small topper.

Feeding advice:Feed only a small amount, cooked soft and crushed or pureed, inside the daily treat allowance and within about 10% of daily energy intake, with complete dog food as the main diet.
Preparation:Rinse dried lentils and cook them until **completely soft** (**raw lentils hold lectins that cause vomiting and diarrhoea**), then crush or puree them plain; use water only, with no salt, oil, garlic or curry seasoning.

What to do after ingestion

Stop feeding and monitor; **contact a vet immediately** for ongoing vomiting, diarrhoea, retching, trouble swallowing or lethargy, and never induce vomiting or give human medicine at home.

Benefits

Cooked-soft lentils bring plant protein and dietary fibre at a moderate calorie cost, so crushed or pureed plain lentils work as an occasional treat or a small topper.

Feeding advice

Feed only a small amount, cooked soft and crushed or pureed, inside the daily treat allowance and within about 10% of daily energy intake, with complete dog food as the main diet.

Preparation

Rinse dried lentils and cook them until **completely soft** (**raw lentils hold lectins that cause vomiting and diarrhoea**), then crush or puree them plain; use water only, with no salt, oil, garlic or curry seasoning.

Notes

**Always cook lentils right through**; whole lentils choke and their fibre causes gas, so crush them and keep portions small; **stewed or curried lentils with salt, oil and garlic are out**; **contact a vet** if vomiting or diarrhoea continues.
