I think I'll get him back to the vet's in a little bit, after I've gotten to know him a little better, and thoroughly inspected him both mentally and physically.
I'm collecting info on him for her, and I'll add the dental conditions you mentioned. Thank you!! He looks a lot like KAK's Pearl. I have to remember we've only been together a short time; he's so affectionate I feel like I've known him for years!
