I have added a sort of second level to my cage - the top of the drawer/bed and some board covered with carpet attached to one corner. This second level type thing is very stable and has quite a large surface area. The problem is the ramp though - I made a wooden ramp with steps glued to it and it's not very steep but she won't go on it. When i put her on it, she'll walk up to the second level but she won't go on it on her own, even when i put veggies on the second level. She can smell the veggies and stretches herself up to the second level to try and get them but she won't use the ramp, if i put any greens on the ramp she'll stretch up and take it without walking on the ramp. Anyone have any suggestions?
