Thanks, everyone
I had attached the maximum 10 photos on the ad I placed, and I think that helped in generating enough interest that I could afford to be selective. It can be hard to resist cute kitten photos!
What I failed to realize, now that Newt is without two of his siblings to play with, he has focused more of his attention on me and his mom during play time, which I wouldn't mind if only he played nice and didn't use his claws so much.
