Can a hedgehog use another animals old cage?
Not usually. If the other animal died or was sick, the cage would have to be sterilized with lots of boiling water and disinfectant. A hedgehog can catch pneumonia from drafts in a wire mesh cage, no matter how far from a window. Any used cage would need a thorough cleaning with a little boiling water and disinfectant. It is usually best to give each hedgehog a new cage.
