ok i have a big problem these rats have been together for a month and a half, and all of a sudden one of the females went crazy i mean completely nuts. she was attacking the other girls and biting herself. the other girls was holding her down it was so weird and the big male was hiding. then the other girls hid and she still was freaking out i had to catch her with a pair of tongs and she started attacking the tongs. usually i can hold the rats they are in my house so i hear them all the time i could hear her from the other side of my house. she is from pet smart. what should i do. i dont want to kill her and now im scared to use her as food incase she has something.
