NOTE: I started this post quite awhile ago; believe me, it's been edited down somewhat. I could talk about my rats for forever and a day; I've decided I should stop right about here and just post what I've got. If it seems to end suddenly, now you know why.
Also, change the beginning from, "A few days ago," to "A long time ago, in a galaxy far away. . ."

A few days ago, I noticed this comment: Since I'm new here, maybe you could explain more about your rats. Thanks. :-). It was left by Jennifer of the excellent Jennifer's History and Stuff, which is one of my daily reads. I'd answer her question anyway, because she's just so nice (she even thanked me in advance!) and it's about rats. Throw in that she will be my go-to when I have a history question (I haven't had any, yet, but you never know)(I confess I'll ask James Civil War questions, tho) . . .how can I turn her down? Anyway, rats.

That's my intact boy, Witter. He's a very sweet rat, somewhere between 1 and 1 1/2 years old. He was adopted a few months ago when my gf and I received a phone call from our vet. His previous owners told Dr. G to put him to sleep because they didn't want to pay to treat him--for mites!
(Mites are dead easy to treat for: either you take him to the vet once a week for three or four weeks, where he would get an ivermectin injection, or you give him a bath in medicated shampoo twice (about fourteen days apart), and give him two squirts of Front Line once a week for four weeks. It's no big deal, except for the baths, and it's easier to give a rat a bath than it is to give a cat a bath. I was really angry at those people.
(Anyway, at the time my gf and I were treating our nine other rats for lice--the treatment is exactly the same. We thought about it for about a half-second before saying, "Yes!" and I'm glad we did. He's "my" rat, which really means I clean his cage and pay his vet bills (and Dr. G gives me a break on those since we saved him from having a house rat--he would NOT have put him to sleep if he couldn't have found him a home). )
(Man, that was a lot of parenthesis!)
Witter was named for Brenden Witt of the Washington Capitals. Unlike Brenden Witt, Witter is a very sweet, very licky rat. He's become my personal favorite of all my rats.

My other boys. From left to right they are Kono, Calle, Olie, and Metro. They're named for other members of the Caps (sadly, Calle Johannson is no longer with the team and Glen Metropolit is in their minor league system). They were adopted in October of 2002, from a lady we met online (thru a rat discussion group, people!) who had several litters. Kono and Metro are my Patriot Day boys, having been born on September 11, 2002, and Calle and Olie are a little younger, having been born a little more than two weeks later.
One thing you can't see in that picture is how fat they are--there's probably over three kilo's of rat in that hammock. They're neutered, and neutered bucks (the technical term for male rats. Yep, females are does) tend to get really fat. They were neutered because at about four months, they hit puberty, and as sometimes happens, they started fighting--especially Olie and Metro. After they got emasculated, it was Calle and Kono's turn. . .
Of course, we had clues they would be huge. Here's our first picture of Calle, when he was about three weeks old:

See? He's eating. (Sorry about the pixelation; he was a teeny-tiny little rat and in the process of cropping/resizing/enhancing this pic. . .things got a little screwy.)
