Bertie likes strands of hemp strings that he can toss around and chew, also loo rolls filled with hay and herbs. Cardboard boxes made into a tunnel are great, and are good for chewing on. He has a couple of knitted easter bunnies that he puts in his mouth and runs around with...it's really sweet!
I bought him a couple of shop toys but he's not at all interested in them! He likes willow branches to toss around and chew on as well.
