A few weeks ago I decided to move my cat's litter box to the basement. Since my cat is unable to open the basement door on his own, I left the door open, or tried hard to remember too. it had been my intention to install a cat door...and this past Sunday, I did.
Watching Oliver learn how to use the door and figure it all out had been interesting. Fortunately, he has not left any droppings in frustration. There was one occasion where he planted himself near where the litter box used to be and then just start screaming...at which point I picked him up, brought him to the cat door, and just held him in front of it and gave a slight nudge. I had to do the nudge thing a few times.
