I just got a robo female hamster like 4 days ago n I have noticed that she sleeps in her wheel a lot!! She made her nest there n she can barely use her wheel, every time I take it out she goes running in her wheel n then makes her nest again!! I tried putting some paper tissues on her actual bed in the cage but today I found them in her wheel! Just today she started scratching herself idk if it was more than usual but it didn't seem normal to me! I used to have another robo that I got about two weeks ago who died shortly in the same place.. I did change the wheel n the water bottle place!! I became so obsessed with this one since I got it 2 days after the other one died so I'm really worried :( I have an OVO habitat.. oh yea she eats in her wheel too :( is this normal?
