I bought this for my Syrian hamster. It is a spacious hide so even the largest hamsters and rats could fit comfortably in here. It does take up a lot of room but as it can hang from the ceiling it is easier to find space for it. It is very secure when hanging and easy to take apart to clean. My hamsters have not slept in here but like to climb up to it to sit and eat.
Great addition to my syrian hamster's cage
It is quite a large size so would be great for large syrians or possibly rats. I like how it can be put in the cage either way up and this helps when changing around the cage to make it more interesting and stop her getting bored. Easy to clean and store as the two parts come apart and can stack together.
Initially I filled this with nesting material in the hope that my hamster would sleep in there, although she has never done this, but still likes to climb around and through it.
Good quality however way too big for hamster cage.
