Black Beans

Phaseolus vulgaris (niger)
Also known as:black beans, black turtle beans
CatCaution

**Cats are obligate carnivores, so legumes serve no nutritional purpose**; **raw or partly cooked beans hold lectins that cause severe vomiting and diarrhoea**, and the fibre brings gas, so keep them to a rare small amount, cooked soft and mashed.

DogSafe

Cooked-soft black beans bring plant protein and dietary fibre at a moderate calorie cost, so crushed or pureed plain beans 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 beans, soak them well, then cook until **completely soft** (**raw or partly cooked beans hold lectins that cause severe vomiting and diarrhoea**), and crush or puree them plain; use water only, with no salt, oil, garlic or seasoning.
