Why?
Quinoa is a starchy seed with some plant protein, but that protein doesn't suit an obligate carnivore: plants don't provide the taurine cats need. Its outer layer is coated with saponins, bitter compounds that can irritate the digestive tract, which rinsing before cooking removes. It also contains oxalates, so it's best avoided in cats prone to urinary stones.
How much?
A teaspoon of rinsed quinoa cooked in unsalted water with no seasoning, once in a while. No quinoa salads with onion, garlic, dressing or lemon.
The risks
- Poorly rinsed quinoa: digestive irritation
- Salads with onion, garlic or dressing
- Bloating or diarrhea if overdone
- Oxalates: caution if your cat has urinary stones
Your cat ate some: what now?
A little plain quinoa isn't a problem. Watch for vomiting or diarrhea over 24 to 48 hours. Call your vet if symptoms appear or if the dish contained onion or garlic.
Better options
For protein that actually counts, nothing beats a small piece of plain cooked chicken, turkey or fish. Cat treats are formulated for their needs too.
Common questions
Is quinoa a good protein source for cats?
No. Cats need animal protein, which supplies taurine, among other things; plants don't contain it. Quinoa can be a tiny extra at most, never a base.
Can cats eat quinoa salad?
Usually not. Quinoa salads often include onion, garlic, herbs, lemon and dressing. If you want to share, set aside a spoonful of plain cooked quinoa before mixing.
