My hamster loves this he is always in it :):):):):)

My guinea pig loves this and so do I. You can see what your guinea pig is doing even though he is in there trying to hide. Ours runs on top of it to get a view of what we r doing and jumps down. He loves it. He does it over and over again. His exercise I am assuming.

I bought a small one for my mice and a jumbo one for my guinea pigs. They love to climb on it to play. The top is one of my guinea pig's favorite place to sleep. I have three guinea pigs and they can all fit in it together. They absolutely love it :)

While these do take up more space than the igloos, they're easier to clean because they don't have the little pegs that igloos do on top. My mice like the two about the same and switching between the two gives them a lot of variation in their cage.

My hamster loves this little barn. He doesn't chew on it and he has had it for 3 years and it still looks like new. It gives him a good place to sleep and to store his goodies.

I bought this for my bunnies as a Christmas gift to help them get more exercise and they love it. I believe I have the jumbo size. It would be too large to put in one of their cages so I just put it in their playpen when I let them out for their daily exercise. My younger Angora rabbit (3 yrs, 4 lbs) runs up this and sits on top of it all the time. My older Lionhead rabbit is a little slower and larger (6 yrs, 6 lbs) but she also likes to sit on top of it or hide out inside it. If you have decently active rabbits or are looking for something to help them get more exercise, I would recommend this!

I bought this barn for my guinea pig when I got him and he loves it. I love it, however, it takes up alot of space in his cage. Petco only had one size in when I was buying and he barely has any room left to play in his cage. So if I were you, make sure you have a pretty big cage before you buy this.
