The other two haven't come out to play with us yet. The calico (GoGo) started to come out yesterday but hissed at me when I got too close. The orange one (Fred) hasn't even wandered out of the box while we're out there.
Last night Barney (the stray tom cat that we think is the father) was on our deck and limping. I also noticed that Silly had some injuries, so I think they may have fought the skunk off together? Weird thought for a Tom to be protecting his kittens... but maybe he was protecting Silly while she was protecting her kittens? He's around a lot and if he weren't the father, he'd probably have killed the kittens by now.
