I gave these to my grandferrets for Christmas. I bought two because they are so chubby but they sleep in just one. They love it!

Pros: Ferrets love to snuggle in it

Cons: none

My ferret loves to spend time in his sleeping bag. I would recommend this to anyone who wants a warm comfortable place for their ferret to sleep, rest, or just hide.

Pros: comfortable, cozy

Cons: none

My bunnies pawed at this a little, but didn't seem overly impressed. A $2 fleece baby blanket works just as well.

Pros: It's cute

Cons: expensive

These sleeper bags are nice because they are well made, easy to wash and easy to attach to the cage. I opt not to buy them though because I prefer to make my own, which is cheaper, plus I can choose the fabric.

Pros: Comfortable for small animals

Cons: can make one cheaper
