Comments: I purchased a smaller version of this when I got my first rat. He hid in it all day long, shredding up pieces of cardboard and making a huge nest inside. The double entry was a big hit with him - he could stare out the front and watch for things, then sneak out the back if I wa going to pick him up. I've since upgraded to this size with the addition of another ratty. They both cuddle in it, making nests out of bedding (some of which is included) and bits of cardboard. They also like rolling around in it.
<br />I alternate between 2 of them, with the other being used as a fun hay holder for the rabbits. Once the hay is gone they carry around the hideout and munch on it.

Comments: My chins all hate this ball and prefer the grassy hutch instead. This ball has open ends on both sides so it defeats the purpose of a hidey hole. As much as chins love grassy toys they just wont touch this one.

Comments: this one is not big enough for guinea pigs..at all! all they can do is eat it! i use it now to put fresh greens in..they seem to like that! i plan on getting the bigger one to actually use as a cozy sleeping place!
