Carl is a hairless.

See Lenny's page for details on how I came to obtain him.

Carl is the largest, and the most reserved of the three. He is less inclined to play and leap about, and seems to get the most scratches and wounds. Hairless rats wound very easily due to having no fur to protect their skin, and each one of my three seems to have a new scratch on them daily. As he has gotten older, he's shown he is quite a dominant rat, and possibly will be an alpha one day. He is also the one of the three who is least keen on being handled, and clearly his scratches are the result of his dominance scuffles with other rats.

In the first few days of my owning them, Carl and his brother Frasier decided to make a nest in my mattress and required 2 straight hours of coaxing, mattress-cutting and chasing them around with hands and torches to get them to come out. For some reason, Lenny remained away from the whole ordeal. At the time, neither Carl nor Frasier trusted me enough to come when called, and were not much interested in food either so it took having to pretty much cut the mattress in two to get them out.

Why Lenny? My friend Mick named both Lenny and Carl after Simpsons characters.
