Frankie's face is back to its normal size... and in place of the old wound is fresh, healthy, pink skin. He's been combative, but my boyfriend and I have both managed to warm compress his wound once a day. He's going to be on the antibiotics and anti-inflammatory drugs for another week and a half... but so far so good.
I just want to say, to anyone out there who has or will ever have a glider with an abscess - you can do it. It's scary, but with a prompt vet visit and careful care of your glider, it can get better. My poor baby was abused by a previous owner, and after five years of attempting to bond still will not allow me to handle him. Yet... I have been able to help hom heal. Don't get discouraged!
