It does seem to be staining, her stools are fine, dry as expected, there are no wet areas in the cage, she is on a wire base with wooden perches and platforms, i change the sawdust once a week. I just feel like shes become a mom and given up on her appearance haha! (jst like us human mum do)
Ah well maybe she'll clean up once the kits have 'left home'
Thankyou
