Quoted from Rat_Tomago:Dude the grey one is a Tonkinese.(Half Burmese / Half Siamese) They are a wonderful breed and very vocal. They also live almost forever because of the Burmese in their blood.
Welp you got the very vocal part right at least. They've both bonded to me pretty hard since I weaned them and work from home and am around all the time. When I go on business trips they wander around the house looking for me, they follow me from room to room meowing for attention.
The mother was all grey, the father I don't know, but I suspect he was a black masked/socked siamese a bit like the one on the left that I've seen around. She was a stray and we caught her moving her litter under our house. When we judged the kittens were old enough we trapped her (I took her to the vet and had her spayed before we released her again) and got the kittens. Which makes it sound easy, and not an all day ordeal involving breaking holes in our walls to pull them out!
Burmese can be all grey right? You could be totally dead on.
