Glad it was nothing real serious.
Sounds like Stix might be having jealousy issues. Is there a way that you can give him some extra attention by himself? Explain to him that you love him, but you need him to be friends with Kota.
That abscess will be gross when it bursts. If you could lance it yourself, it would be better.
Get together supplies you'll need, first. Get some sterile saline solution, or some other wound cleanser; Betadine will work. Peroxide can kill delicate tissues, so avoid that. You'll need a syringe with no needle, a sharp
, sterilized X-Acto knife or single-edge razor blade, and some gauze or a bunch of cotton balls.
You can make your blade sterile using rubbing alcohol or a flame.
Have a wad of gauze or cotton balls handy, and make a little cut toward the edge of the abscess. Squeeze the contents out, blotting up the mess as you do. Fill up a syringe full of saline and squirting it into the wound with one hand, have more gauze or even paper towels ready with your other hand. Do the wound flushing two or three times, and then bandage it up. Give Kota a fresh bandage every day, and watch to make sure it's healing okay. Oh, I forgot to mention treats; give her lots of treats and lovin'.
That was easy, wasn't it?
