If it is infected or a cyst, a very warm (read: hot, but don't burn her) moist compress may help to draw out the cyst/infection. I'm not sure how she will like that, so it may be difficult....but it could also help if you are able to get her to allow it.That bump on Coco is distressing her and she scratched it last night. I am going to put some antibiotic ointment on it (after I get some) all I have is Vetericyn + spray.
right now, she just wants to snuggle up with me.
The bump looks to me like an infected peck or scratch, but I don’t know.
