He's healthy as a ratty can be. He'll be 5 in August. He has some furr loss, but they did just get over a lice problem.one of your rats is four!!?? i've never heard of them living that long!
well, i've seen people say "sometimes they can live this long..." but never actually heard of someone that had one.
does he have hind leg paralysis or anything? he looks pretty good for his age!!
