Almost every species of animal on earth has it's own Herpes virus. It's an ancient virus that was living with us when we were still in the swamps. Which explains why it is found among almost all species of animal.
Anyway, in humans the Herpes virus causes cold sores...(which are ulcers) on the lips, but they can be elsewhere too... I've seen them on my friend and they've been across her face. In felines, the Herpes virus generally cause ulceration in the eyes. I've never heard of them getting cold sores from herpes on the lips....but I'm not saying it's impossible. I just don't know. There's some links to Feline Herpes sites here...My cat was recently treated for ulcerated eyes, and the vet diagnosed Herpes.http://www.cat-world.com/Healtha-k.htm#Herpes
