I currently have a IMAC fantasy cage with no extensions (just the ground level and the plastic one) and i was wondering whether i should update to a bigger cage for my russian dwarf hammie, Bambi. She seems to be quite restricted in her cage; she is always running round her cage, back and forth, and climbing up the bars and flopping down. She has nibbled on the bars once or twice but not a lot. Should I save up for an extension to add to the top of her cage or should I get a bin cage or even an ikea detolf?
thank you in advance
