Perfect hamster cage - do not buy any other.
This is the perfect cage for hamsters. It gives them a vast amount of space to run around in and climb. My floor area has 2 bridges, wooden nest box, potty, wheel and still she runs around like a loon! Upstairs added long wooden bridge, cardboard tunnel, 2 hammocks, a hanging nest, 2 ledges, still plenty of room. Hammy goes crazy running round and down, even refuses to go into her ball for floor time. She'd rather climb up onto the plastic ledges than use the ramps provided though.
