Chocolate is very toxic to hamsters and should never be given, not even in small quantities.Affected hamsters should be taken to a vet immediately since the hamster will need fluids, vitamins and warmth to help detoxify the body.
If your hamster ate chocolate, you may use a homeopathic treatment which may help it feel better. The homeopathic treatment is Nux vomica
- this can help the hamster feel much better. Nux vomica
may be bought from an animal pharmacy or from a vet.
