It's a measure of how normal kitten fostering has become for us that I realized I'd forgotten to mention our most recent foster. Mabel (the black kitty on top of the box) has only been with us for about a week. After Aaron went back to the SPCA, Marcus was crying pretty much non-stop. We asked for another kitty to give him a companion, and picked up Mabel.
They've been romping and playing like crazy, are gaining weight rapidly, and should both be ready to go back to the SPCA in the next few days.
