Can degus eat sweet potatoes?

Yes, but only a little: degus can eat sweet potatoes. The RSPCA says sweet potatoes can be high in sugar. It says to give them only in very small pieces as an occasional treat. PDSA lists them for only once a month because of the sugar.

How to serve it: a very small piece, rarely (RSPCA, PDSA)

Good to know: None of the degu sources mentions regular potatoes.
