Can rats eat avocado?

No — avoid

No. Avocado skin and stone contain persin, which is toxic to many animals, and the PDSA advises not feeding avocado to rats.

The details

There is no nutritional reason to take the risk. The fruits and vegetables marked safe in this list do everything a treat needs to do.

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.
