"I have a dwarf hamster.she loves to dig and play with bedding,so i thought the down under feature would be great.but when i put her in this cage she didnt like it at all.plus it is very hard to pick up my hamster.and there is no space to put a hideout.and the water bottle is no good.it doesnt have a ball just a small hole,so it leaks.I actualy only had this for a day.i returned it to petco and got a full refund.i just use my original cage.I have a picture of my orginal one"
