I love it because you can take it apart, and it is easy to clean. My guinea pigs seem to like it. It is big enough for the guinea pigs, but it doesn't take up alot of space in the cage. Great product!!

Pros: Very easy to clean.

Cons: none

I bought this for my previous male rat, Jigsaw, when he got hind leg weakness, which made it hard to get in/out of the Super Pet Chinchilla House he had. The Waffle Block house is just the right size. It was easy to go in/out of, and there was plenty of room inside for Jigsaw to sprawl out if he wanted to.
My new male, Willard, now has this in his cage, and he uses the inside to stash his food, but he sleeps on TOP of the house for some silly reason.

Pros: Easy to take apart and clean. Easy to put together.

Cons: No variety in colors, no solid colored homes.

I have several guinea pigs who love to climb on top of their house and being flat on top is a great place to lay down. The one I have is big enough for 2 guinea pigs to fit in. They seem to love it. It is easy to take apart to clean and easy to put back together. Fits great in the corner of the cage.

Pros: easy to clean and strong

Cons: can be chewed up
