Another thing to consider, while no one likes to think of insects or arachnids in their homes, is the possibility of a spider bite. My senior cat, Cirrus, had a sore on his chin that resulted in a lot of swelling and tenderness. The morning I decided to take him into the Vet, the abscess burst and was full of bloody puss. Upon discussion with the Vet, he confirmed that, following cleaning out the wound, that there were multiple bite marks by a spider that had necrotizing venom. In Texas, that could easily be a brown recluse, though we had no conclusive evidence. Cirrus' wound was cleaned out and he was given a long-acting antibiotic injection to prevent any subsequent infection.
I asked about feline acne, and the Vet said that there was a significant difference in how the lesions present, but that metal bowls are always far superior for feeding cats...especially older cats with immune-suppression.
Another possibility, given that your cat has two separate lesions at two distinctly different locations on its body is that there was a bite from another cat, which might also cause an infection and resulting abscess. The infection is likely to make her less personable and be inclined to want to sleep more, as she may have a fever. Another really good reason to get her taken to the Vet's for assessment is if she is sleeping more, she may not be eating, and if she is not eating, she may go into hepatic lipidosis, which is quite harrowing, and can be life threatening, if left untreated.
My thoughts and prayers are with you and Jasmine that it is something quick and easy to treat. Good luck!
