Chewable but entertaining!
My rabbit love these treat balls. They only get a small amount of pellets daily but I offer them in the treat balls and they have great fun chasing and throwing them around. The odd pellet does get stuck in the lip but it isn't a problem, as I shake them out and offer them to the buns when I collect the treat balls. My only concern is that the rabbits do chew them, especially as the carrots stick out, and they could consume the plastic.
