The vet has declared that Winter is now too old and arthritic for a feeding station on the fridge and a litter in the basement. I'm told that everything should be available to him on one floor, and at floor level, so that jumping isn't necessary. Dog proofing kitty litters and cat food is a whole other problem, but I decided that it wouldn't be the end of the world to keep Winter's stuff in the guest bath.
I took the bathroom door off the hinges and lugged it downstairs - it's solid pine so this was no easy feat - to replace it with the door that already has a cat hole. That's when I discovered that idiot who built my house used different hinges - and I suspect installed all the doors without a jig. So my doors aren't interchangeable.
As a result, tomorrow I get to buy a new door. I'm sure as heck not cutting a cat hole into a solid pine door.
