Yeah, he's young - he's grown visibly in the last couple of weeks. Too young to be allowed out if you ask me, especially having observed his lack of road sense.
He's got long hair - there's surprisingly little cat under all that - and a spectacular tail (that's natural resting fluffiness, not excited bushy tail mode), so I wouldn't be surprised if he grows up to be very Kai-like.
He's quite friendly and extremely curious - he climbed all over the bike trailer a couple of weeks ago while I was hitching it up, and I've seen him approaching random students as they walk past outside. And he followed barakta into the house when she came home from work this evening and ran around exploring.
