Hi, I hope someone can help....my cat Roxy just turned 1 on Aug. 17. For the past 4 months maybe i have noticed what looks like a red bump on her botom lip. i thought at first it was a bug bite but it comes and goes. When it is there it seems to take at least 2 weeks or so to go away and then it comes back a few days later, sometimes in a different place on the lip. My mother has her sister and noticed that she now seems to have the same thing if not something very similar to it....we live in different places so i dont think it is something passed from one to the other. i have another cat (Leo) and he soesnt have anything like this. Does anyone know what it could be and if she needs to see a vet?
