I have two Russian female dwarf hamsters and they share a 25 x 30 x 50cm wired cage from pets at home which was highly recommended for two dwarfs. It seemed cramped with all the chews and toys, so I removed most of the toys which made it a bigger spacing things out.
Rosey, one of my dwarfs, started to bar climb and chew on the cage, because she loves to have lots of toys in the cage. I need to get a larger cage for the two. I want something large and cheap.
The zoo-zone 2 was recommended. Is it a good size or should I look for something else?
