Female, started since I had her at 3 months. She dashes at me in the cage and bites me. ill be wiping up urine, shes no where in site and then she comes out of nowhere and bites me and the girl clamps on and holds on. Thats been happening less, but out of no where she still does it. Or ill slowly pass a hammock and she lounges out at me. She feels bad every time, and then goes hide. The biting only happens in the cage. When shes out of the cage she is a sweet heart and loves getting kisses and hugs and loves hearing her name. She is also having anxiety, im noticing bald spots and its not bugs. I think she is having anxiety scratching like someone picking from stress. She use to hide during playtime in a corner and I could never catch her, had to use a net at first. She has gotten alittle better with that, she comes by me more but she still hides and doent want to go home. 2 days ago she was freaking out in the cage, actually screaming in a box, she was also attacking me everytime I went near her, I finally got her and put her in a separate cage and she hid in a hammock. Next day she was all better. Not sure if she was in heat or a mental thing??? The whole thing confuses me because she does not act like a normal rat. In trying my best to give her the best life but I could use some help and understanding her better.
