Yes definitely. Hay is so beneficial for a guinea pigs diet. (Just be wary of the alfalfa/lucerne kind). Glad they like it

I've only seen the alfalfa hay tunnels before in that shape. Well, if they are younger the alfalfa should be fine -- but once they reach adulthood then they shouldn't have alfalfa at all.
