My non contagious rash

Lily got sent home from school again today and we were told we had to go get a diagnosis from a Dr.  So we did, and apparently she has Erytherma Multiforme - or in other words, an unexplained, non-contagious rash.  It does look bad.  She wouldn't let me take a good shot of it.  Also, you are being introduced to her new lion - his name is Roy, he came back with me from Vegas.  Tomorrow we are off to a different Dr - the vet - apparently I leave home for a few days and everyone gets a rash.
