my hedgehog used to be quite active in her cage. now she is only active when i have her out. when i put her back in her cage she goes in her hut. if she doesnt come out after an hour like she usually does i take her hut out and then she eats and runs on her wheel like normal. i dont know if this is cause im staying up later or what. it has got colder where i live but i keep a space heater at 78 degrees and bought a more direct heat source to put above her cage. i checked her belly and she doesnt feel cold. any suggestions on what to do or may be causing this?
