I have a cat that has been losing fur on her neck for the past month and I am really worried. The first time my cat lost fur on her neck was when I was fostering another cat and she ended up having a fever along with it. That was about a year ago, and she was doing fine since we sent away the foster cat, but she started losing fur again about a month ago on the same spot on her neck and on her chest as well. We took her to the vet and the doctor said that it might be allergies, so she advised us to only feed our cat wet/dry food and give her a bath so we did. After that, she started growing her fur back but at a really slow rate. Her fur was fine yesterday and I could see that almost all her fur grew back, but this morning I noticed that she's losing fur yet again in the same exact spot. I don't know what to do and I'd like to take her to the vet to take an actual test but it's probably going to be very expensive. I know the bald spot seems really small right now, but in the past it grew to be pretty large which is why I'm concerned. Does anyone know what could be causing her to lose fur in the same exact spot?
The first photo is her fur now and the second photo is her fur a month ago after she took a bath, which is why her fur is wet.
