30 - I have quite a large wired cage with navy blue plastic base for Sale. It has 2 fold down doors but 2 of the 6 cage clips are missing! (1 on each side of the cage is enough to keep it secure!) There is a small worn part in one corner but I have kept my rats in there with no problems smile The cage will come with a running wheel, large ball and seesaw, all of which are in the photo! laugh
