My foster mice are currently living in a jill 52.2 and its a wonderful cage but the door needs to be like 4 times bigger than it is. Is there any way to mod it?

This is my cage.

that is such a small door what were they thinking??? you could modify it but just be really careful you dont leave any sharp edges and make sure you use a heavy enough gauge wire that they cannot chew through maybe even a wire coat hanger,
