She was very good about her treatment and was always very patient about her twice a day regimen. It also helped me come up with a better strategy for nail clippings; instead of enlisting my boyfriend to help hold them still while I did all the nails at once, I do a foot every couple of days. They're so much more relaxed that way -- even Fred, the feisty little guy that he is, is a lot more patient with this system, although he never lets me finish a whole foot and I have to do just a few nails before he freaks out.
Total, I spent $80 on vet visits, $92 on antibiotics, and $20 on probiotics, for a grand total of $192 on a guinea pig abscess that may recur, require more antibiotics, cause a resistance to the antibiotics which can cause a whole host of new problems, and eventually require expensive, invasive surgery. Fingers crossed that the whole episode ends today and no more problems develop.
