This cage is fantastic when put together with lots of room for extras. A bigger wheel is a great extra to add and some hammocks, the food bowel stays in place and its very easy to clean, has a great locking system so hammy wont get out.
My only gripe about this cage is the water bottle, it has a little hole for the water to go through and it stops working so hammy gets no water, I would really recommend having a 2nd water bottle in the cage as a backup otherwise hammy could die from dehydration.
Well worth the cost for this cage.
The ladder that goes into the house is not held anywhere near secure enough & has fallen down, as this is isolated, it is not safe & the hamster can fall down or not be able to get back in the house!
Also the 1 ball bearing in the water bottle makes it extremely difficult for the hamster to be able to drink, I had to buy a separate bottle as my hamster became so dehydrated that he was not eating either!
It is the best I have seen for activity though with the various floors!
