Kassie's going to the vets tomorrow morning to get it checked up but in the mean time I thought I'd ask you folks about this. I found a half pea size lump on top of her right leg, right above her knee. It's hard to the touch, smooth in appearance and the skin is translucent with what looks like a whitish/yellow color underneath. It almost looks like a huge white blackhead or pimple that if you squeezed it, it would pop (sorry for being gross, hope you're not eating at the moment). Don't worry, I won't squeeze it. What could it be? I'm kind of freaked out about this. I have a picture of it. It's blurry, best I could do.
