Little Lola Grace loves her digging box - I use a large, shallow, rectangular storage box (without the lid) and it's filled with nice soft straw and some timothy hay for nibbling. She sits in the sun in the garden in the middle of her straw, nibbling on her hay - very civilized!! Benson sometimes hops in beside her for a groom but mostly Lola uses it.
They also have a paddling pool with a lid filled with (not water!!) screened soil. Lola (again) likes to roll in it and digs occationally. Benson, again would rather run up and down as fast as he can!!! :wave:
