I have the following cage available for collection either at Monmouth, Gatcombe, possibly North Somerset, or Blenheim:
It is in very good condition, although the picture is a different colour to mine, the one I am selling is a blue base with black bars. The wired levels are removeable and it comes with a small solid wheel, house and water bottle. It is a flat pack cage so handy for storage but is very sturdy when built and has a carry handle on the top.
The dimensions are 57cm long x 42 cm high x 31cm wide.
