Can rats eat rhubarb?

Better not: rats shouldn’t eat rhubarb. The RSPCA lists rhubarb among harmful foods to avoid, and its NextGen site says to avoid it too.

Good to know: Rats can’t vomit, so the RSPCA warns that even a small amount of something harmful can kill them. If you’re worried your rat has come into contact with anything harmful, the RSPCA says to contact your vet immediately.
