So i have two male rats Ringo & Abbie, they're my first set of rats and they're about 4 months old. They're sweet little boys with very different personalities, i bought them together when they were about a month old. At first i was concerned that they might be fighting, sometimes one will squeak on its back and the other one will be hovering over them, yet it's a pretty mutual thing. Neither rat ever seems to be hurt, yet i did some research anyway and felt a little better when someone told me they were probably just playing or having 'petty arguments'. However, yesterday when i was gone, my family heard one of my rat's squeal very loud, so loud it woke someone up, and could be heard throughout the house. Abbie had a cut on his tail and blood on his forehead. I'm not sure what to do now, i would hate to separate them, i simply don't have the room for two cages, yet i don't want to make a homeless rat =(. And i wouldn't want for the other rat to have to live a solitary life ... any suggestions would be great . .thanks!
