I work at a cat rescue and someone just brought some cats to me at my house.. They were let loose after their owner died, and came to live with these people. Anyway, i noticed one of the cats, a gorgeous medium-longhair dilute calico, had a bulge to her upper lip on one side. I took a look at it from underneath and it looks like some sort of fungal or other infection. It is pretty swollen and has got to be uncomfortable. Is there anything i can do for her before i can take her in to our vet on Monday? I don't think her life is in danger by any means, but it looks pretty nasty.
