I rescued a mouse about 2 weeks ago. She was loose in the dorms where I work sometimes. It was very obvious that she had been someones pet and she fast became my boyfriends new sweetheart, Puck. We realized pretty quickly she had a couple of small tumors on her and in our research found that mice can be prone to these. Within days of us bringing her home her fur became smoother, the tumors seemed to have gotten smaller, she became more active, she built a nest in the corner, she plays in her food, her poops got more moist and larger. She seemed SO much better. Two weeks later she even seems a little thicker (not really fatter just healthier) but now the tumor on her shoulder area is beginning to lose fur and she look red and angry. I am not sure what happened. The tumors even looked smaller like they might have been abscesses that were going away.
1.) Should we take her to a vet or is he just gonna tell us bring her back when she starts to suffer?
2.) What can we do for her to help the fur grow back or be less angry looking? She seems normal and happy and fine but that can't be comfortable.
Also we got her a little buddy who we believe may have been pregnant when we bought her, Alexstrasza or just Alex. We introduced them and they seem ok but the new mouse seems rather territorial. They would play fine unless Puck got near Alexs's Wheel or igloo then Alex would wrestle with her and chase her off in a mess of squeaks and flying shavings. We separated them again but now I am confused.
3.) Are we going to ever be able to have a friend for Puck?
If Alex is pregnant that is probably where the territorialness comes from would be my guess.
4.) If we were to keep a couple of Alex's baby girls would they eventually be able to be integrated with Puck happily? or are they just gonna keep beating up on her cus she is sick...
