Query: Versatile pet amusement!

My bunny was only moderately interested in this ball. He gets unlimited hay so he doesn't want to chew on more dried straw I guess. But my rats...they LOVE this thing!! I put a string through it and hung it up in their cage as a hammock, and they will not stop snuggling in it. They prefer this over their soft fleece hammock for some reason. I think they like the texture. I have had 4 rats, and they all loved it. They don't even really eat it or anything, they just like to be inside of this thing. Plus, it is very spacious for smaller rats. They can roll around in it too. You should definitely give this a try if you have rats!I heard some rabbits go gaga over it, so my bunny is just weird, I guess =)
