The last ringworm I had was after my daughter in law had come from out of state and brought her cat. I couldn't figure out where in the world I got it since it was on my upper leg. Several week after returning home, she called me to tell me her cat was discovered to have ringworms and I had a persian cat that would allow NO grooming PERIOD! My cat never caught it but I did! He needs to be isloated PDQ!
