Have Cat Questions? Ask a Cat Vet Online.
Hello, this is Dr. Jess. I am sorry to hear about your kitty! Is she an indoor only cat? Does she get along with the other cats in the house?
It sounds like she could possibly have an abscess or a cyst. Is there any way to take a photo of the area?
Did it feel fluid filled at all? Or warm to the touch? Any discharge from the area?
So the things I worry about would be an abscess that has drained but the inflammatory area is still remaining, a cyst that has ruptured, in an outdoor cat I do also worry about ringworm (sometimes it can form nodules that scab and crust as well). Whatever is going on, it looks to me that it is severe enough that antibiotic treatment is necessary. I would recommend scheduling an appointment with your vet to get it looked at and get her some antibiotics. In the meantime, you can try applying a warm wet washrag for 10 minutes to help increase any drainage and loosen the crusting (may help you see the area better), and apply a triple antibiotic ointment such as neosporin several times a day.
Unfortunately, no veterinarian who is online is going to be able to call in a prescription for you. Legally we have to have a doctor-patient relationship which means we have to examine a pet in person within the past year to prescribe any medication. I am sorry that I can't help you further.
There are several different antibiotics we might use, depending on how bad the area looks (it is hard for me to tell without seeing it in person). Amoxicillin is the cheapest antibiotic, Clavamox is another that is a little more broad spectrum. These are both safe in nursing mothers.
That isn't to say that there isn't another antibiotic choice that would be appropriate, but those would probably be the first choices and safest for nursing cats. Be sure to let the doctor know that she has nursing kittens.
