Hi. My cats, I have two, male and female, have these lesions all over them which started out under the hair and now the hair is falling out and they have open sores all over them. What do you think it could be?

If both Prince and Jade are experiencing the same lesions, I would be inclined to think that they are suffering from a contagious skin disease such as ringworm or mange. I would have them both seen by a vet in the morning. The vet can use a Wood's lamp, fungal culture, and skin scrapings to diagnose what is causing their lesions, and can prescribe treatment for them. If they do have ringworm, you will need to disinfect the home as the spores can live in the environment for up to 18 months. http://www.livestrong.com/article/49666-rid-home-ringworm/
