The details

Keep cups and glasses out of reach while your rats are out of the cage, and give them only fresh water to drink.

What to do if your rat ate it

Call a vet straight away — ideally one who treats exotic pets — and don't wait for symptoms. Rats can't vomit, and the RSPCA warns that even a small amount of something harmful can kill them. Tell the vet what your rat ate, roughly how much and when, and bring the packaging if there is one. Don't try home remedies or human medicines: the RSPCA warns these are very dangerous to rats.
