Hi, may I answer your health queries right now ? Please type your query here...my mother is 86 years old and still living in her own home. She has two feral cats from 12 years ago, and they are now domesticated. She has complained about bites on her legs which are large welts, red, and take several weeks to heal. I thought they were bug bites, but her physician says that they don't look like bug bites, but more like an infection caused by the cats' nails kneading into my mom's legs. What do you think, and if so, is this harmful to her health?
