they have these in the petsmart hamster cages, so when i got my hamster i got him an igloo for his new cage. we put some hamster fluff inside the igloo and he loves it.

Pros: --

Cons: --

Our Hammies just love to fall alseep all cuddled up together inside these things, they do sometime chew on the edges so we did have to replace them once or twice. We no longer have Hamsters, but if we ever do have them again, we would get another igloo.

Pros: Gives hamster privacy, they love them

Cons: take up space in cage

Our piggies love this igloo, but three of them can't really fit into it - 2 at the most. One has to settle for the alternate box. The igloo is very easy to clean, and doesn't have edges to get chewed. I highly recommend it!

Pros: easy to clean, durable

Cons: a bit small for multiple guinea pigs

My Guinea pigs love their igloo, Patches is even more into the Igloo. He will lift his head just above the entrance to the igloo and push up and move himself around, He's like a little turtle with the green igloo on his back.

Pros: My Guinea pigs love it

Cons: Takes up alot of their cage space

We had a Guinea Pig come into our shelter which we get very few of. We bought one of these for it and it loves it. It is so cute.

Pros: inexpensive

Cons: none
