oh, hai. we were just going through your library, looking for some good books. it's important to start reading to the youngsters early on.
On the bright side, they've all moved out of the bedroom [yesterday], completely, which means that I can shampoo the carpet, move the bed [now that it's not sheltering terrorists], and put up the last set of bookshelves. Also, mom cat has eschewed the kitten-sized litter pans I had put out, and has them using the big-cat litter boxes that I've installed in the library [which would be the breakfast nook in a normal person's abode].
Allowing them to scatter their toys and my books all over the library floor seems a small price to pay in return for the increased efficiency in toilet training and and the fact that the dog, curmudgeon cat, and I can finally sleep in peace and quiet with the bedroom door closed.
On an entertaining note, mom cat has also introduced them to the dog-and-big-cat water bowl, which is now serving double duty as a tiny-cat wading pool.
