Darling Man picked him up at the bus stop and Z was moving quite stiffly. When he saw that, he asked and Z told him his neck hurt. Then Darling Man did what I should have done this morning - he looked. There was an angry red bite just inside his hairline - and swelling that was growing down his neck (that light u-shaped blob on his neck). That scared him, so he called me and asked if he should take Z to the doctor. Yes! I would call ahead and let them know he's coming.
They got home shortly after I did. It was not a spider bite, which I'd feared, but rather a flea bite that had gotten infected. Since Yoda's been sleeping in his bed, I'm not terribly surprised at that. I was surprised at how violent a reaction he had because he'd never had one like this before. Poor guy - I guess he's got my allergies to insect bites!
I need to go pick up his prescriptions - ointment for the site of the bite and an antibiotic for the infection. All I can say is that I'm so grateful it isn't more serious.
