Spearmint?

Can guinea pigs eat spearmint?

 

[Sarah from Chucklebunnies]

They can eat mint. I must admit I don't give them much of it, or all that often either. One of my herd likes it more than the others.

I have given the mint you use in mint sauce, and the fuzzy mint which is much less strong (forgotten the name). They prefer the mint sauce one.
