My cat had a small scab on her anterior neck. She scratched it and by yesterday it was a dime-sized open wound. I cleaned the wound and applied some antibiotic ointment. By this morning it was larger ( she keeps scratching and licking the area) Again, I cleaned it and applied ointment. I also tried to contact our vet, but he didn't call back. This evening the wound is even larger--about 1.5 x 2.5 cm. The wound is pink, clean, and has no odor or discolored drainage. I have clipped and filed her claws, butr don't know what else to do. An Elizabethan collar won't help, because the wound is right at the area that the edge would rest. Any suggestions?
