My family adopted these adults yesterday! One is 4 years old, one 6 with a missing foot and end of tail. They are soooooo gentle and sweet. They've lived together for 2 years, but I know we might have to separate at some point. Aren't they adorable???
You should separate them soon, yes. It looks like they both have some nipped toes, as well, unless it's just the angle of the camera. The sooner they each have their own space, the happier they will be
