Found A Lump On My Cat Options

[Leighann]

So I found a lump on my cat Baby's lip on Wednesday morning (its just off the lip in the hair line). I won't be taking her to the vet until tomorrow, so my imagination is running wild. I hope its something like feline acne or a simple abcess or something to do with her allergies. It doesn't seem to bother her, it was red Wed, fine yesterday, and red again today (she must be itching it - though I haven't seen her do it) I am so worried already though cause it was this time last year when Homer started getting sick, and he was gone by Dec 24th. If it is the C-word, I pray we caught it early and can treat it. Does anyone know what to look for if it a simple lump, or a bad one??
Thanks,
Leighann
