My poor guy is dying. His cagemate died this summer in an accident. That is when I got this guy, he would not accept new cagemates. He is 2 1/2 approximately. My vet said he may have to be a solo rat and get lots of attention from me. We spent a lot of time together every day. He is dying now. My question is this; do rats usually go off to die alone or should I be with him? Please, someone help!
