I Need Advice Regarding My Elderly Rat?

This decision really is for you to make . Your decision will be based on what you believe and is what you believe is right . I once had to put my dog " Dona " to sleep . She would pee on herself , she had arthritis , and had heart worms . She was suffering , so i let her go . Your rat is suffering , and i would put him to sleep because he doesn't have much of a life anymore. The thing is if you should let him die in his own time . He's going to die sooner or later , let him go to sleep now and stop the suffering . I don't know about the fees . You should call a local vet and ask all those questions to him or her . I hope this helped . I feel for you . Let gremlin sleep in peace .
