Are you hand-feeding him? Three weeks is a long way from being weaned!

We've had feral kittens ranging from "can be picked up and held immediately" to "if you put your hand in reach, you're going to draw back a bloody stump*". If they're young enough, most of them will gentle down fairly quickly.


* I still wish I'd thought to get some video of Mr. Snarly when he was first caught. That was an AMAZING spit for such a tiny kitten!
