The mother cat apparently had no objections to the Gabby-smelling crate or the barriers we put up; we saw her sitting out there by the shed this morning, so we knew she didn't move the babies, and when I went out and peeked a little later (after she left), the kittens were all still inside the crate, cuddled up on the mattress pad in one big pile of fuzzy fur. We're still trying to figure out exactly what to do with them - we're reluctant to just grab them and take them to the Humane Society without having the mother along with them - but at least they're protected from rain, etc. in the meantime. We're going out of town for a couple of days starting Thursday or Friday, to go up to Georgia and see the daughter of our relative that just died, so we have to do something with the kittens either today or tomorrow. I'll keep you posted.
