Well, last night I was checking on my mice and found my oldest male breeder mouse laying prone in the tub. His belly was very swollen, his eyes were goop'd shut, and he was basically unable to move. I did a little investigating and found feces stuck to his butt with a big chunk of a wood pellet in it. It looks like he ate a few pellets of Woody Pet and got his bowels impacted... Anyways, after a little hesitation I went ahead and made the decision to put him down. Cervical Dislocation was really the only method available to me at the time, so that's what I went with.

I was sad to see him go, but it really looked like he was suffering, and likely wouldn't have made it anyways. I can always replace a breeder, but watching them suffer just isn't something I want to do. Now I just have to find an appropriate replacement, and figure out how to get him introduced to them without them killing him (already happened once with this 0.2).

Also, I've been keeping an eye on all of my others. Male, female, young and old. So far nobody else is showing any signs of illness. I did have dreams all night, though, of waking up to dozens of sets of eyes all goop'd over with crud... :-(
