Tonight, I've rescued a black dsh kitty and three of her kittens (also all black dsh). They were learning to play under parked cars on a way-too-busy residential street. That struck me as being a particularly bad thing for them to learn, and one that would almost certainly shorten their lives.
Kittens appear to be 10-12 weeks old, and not too scared of people. Mama alternates between being affectionate and being hissy. I think food is making her calmer, though.
Back to check the trap; I think she had a tabby kitten, too, so I set and baited the humane trap. If I see no kitten tonight, I'll check again first thing in the morning.
Wish me luck!
