Thanks for all the help. I have great news- Today we had to be in
town all day to help Grandma with a yard sale, so we took the kittens
(since we would not be home to feed them).
A family came by and said they had a mama cat who has fostered babies
before, and the mama currently had a couple of kittens the same age as
ours, as near as we can tell. We exchanged numbers and addresses, and
they took the kittens home to see if the mama cat would take them.
She did! She began licking them immediately, and we understand they
are making themselves right at home. We can visit them whenever we
like, and when they are old enough to be weaned, we will take them
back.
