Vinny looks so so sweet! I'm just slightly concerned if he's not feeling well or just sleepy, as his ears are down and he's squinty on both photos (but he could have just gotten up!) Edit: looking at the photos again, he just looks sleepy! He's too cute!
You could go with the girl vs. boy argument, as syrian boys tend to be more docile on average, it seems, and girls more hyper and lively
It varies on individual basis, so you'd of course have to see for yourself. Good luck!!!
