Hi all,

wondering if any of the vet-types can help ... one of my cats has been obsessed with rubbing his cheek scent gland (just one) to the point of open sore. He doesn't scratch it, just rubs it. I have no idea why ... thought it was healing but it isn't, it's about the size of a 1c piece ...

I'm going to take him to the vet tomorrow, wondering if there are any questions I should ask etc or any ideas as to why this would happen?

The googling I've done suggest its an allergy, but its just on the one side of the face only, and he's not scratching it with claws as if it was itching. So I'm thinking it's more behavioual for my little man.
