Growth??

i have a kitten, and well we have just got the house fumigated(sp) because of fleas etc.. on the side of her leg.. she has like a lump ?? at first I thought it was just hairgrowth because shes so hairy (persian) but my mum thinks it's a lump.. its been bleeding you can see but its dry blood shes had it since we've had her. But we never thought of it. It isnt hurting her atall and shes fine etc and we've had her since June..

Im panicking.. shes going to the vets at 4 oclock today..

It could be anything, but if she's had it for a while, it could have been an abscess or a cyst or something like that. It's a good idea to get it checked out, so it can be treated for infection, at least.
