Well I brought home a box of kitten chow, and that was the end of any interacting with the kittens. They were chowing away on it alright :)
I can also tell they are getting to be about ready to go back. I was saying the other day how good they were when left to roam in the bathroom they are now in.. well yesterday I noticed they took all the toilet paper off the roll, they knocked over a basket of stuff, and they even started attacking the rubber duckie..
