Oh no, I'm so sorry ! That can be very serious, infection from cat bite is no joke ! The clinic cat should not be roaming around and if you incur even a dollar in medical expenses be sure to keep track and have the vets office pay. I know the clinic treated you very consolingly during your trauma with Lenny and that this is an accident but the accident was due to their negligence. I hope it does not get too bad but there's a chance that it will. Please keep us updated on YOUR emergency now. Wishing you the best, get to the Dr. ASAP to ward off a possible and extrememy serious infection.
