Hi, havent been on the cat side in a while...still remember Dandy and Guinness? ANyway, we have moved to a new house, that has a basement, so we have the litter box in the basement now and added a cat door to our basement door, for easy access. I thought they would NEVER figure out how to use it. I used food to lure them, but Guinness isn't a big eater, so that didnt work for him...we had it propped open for while to let them in and out, without having to push open the flap...and finally, finally, they are useing it regularly now. It took probably about a week for them to figure it. Guinness even hissed at it once, when the flap closed in his face, after Dandy had just used it...anyway, just curious, if anyone else had kitties that were a little slow to learn how to use the kitty flap/door? Or are mine the only silly ones!
