I just noticed last night, Picachu was barbering the hair on Polly - on the side of her face. I hadn´t noticed anything like this with him before. She would give little yelps, finally get fed up, run to another part of the cage and eventually he would go to her and start doing it again. I picker her up, she has a noticeable amount of hair missing in a little section.
The weird thing is, it´s where her hair is brown in a small patch as compared to the rest of her. Picachu is white and black. I have no idea why he started doing this. Maybe he doesn´t like that color of her hair anymore?? ?(
