Can hamsters eat garlic?

No — never feed

No. Garlic contains the same red-blood-cell-damaging compounds as onion, and veterinary toxicology rates it about 3-5 times more potent. Never feed it to hamsters in any form.

If your hamster already ate some

Call your vet promptly, even if your hamster seems well, and say how much was eaten and in what form. Signs of anaemia, such as weakness, pale ears, feet and nose, fast breathing or reduced appetite, may take several days to appear.
