"I bought this product for my guinea pig and he fell in love with it immediatley. He absolutely loved it, and enjoys sleeping in it. It is very waterproof, for when my piggy urinates and 'goes', and it is very helpful to let him lie around in when you need somewhere for him to just sit, without holding him.
The only bad thing about this product is that the product is much larger than it appears (good size for guinea pigs and ferrets and chinchillas and rabbits, but too big for mice and hamsters) so I bought it at the store. Beware of that, online buyers!
