Oh I forgot one thing have you changed the brand or type of litter
you use recently? Some cats can be very peculiar about what kind of

We haven't seen him do it in action, but it's clearly not a mistake
of "hanging" over the box. He picks a perimeter wall and does his
thing. He's hit about 4 or 5 different spots along the wall. We
thought he might be seeing cats outside and he is marking his
territory, so we closed ALL of the blinds so he can't see out. We've
done this for about 4 days, but this morning we woke up to pee on
the floor near one of the perimeter walls. I think he's just losing
his marbles. He's been pooping outside the box for almost a year.
The Vets never figured out why he is doing that. We've been living
with it. But, cat pee is a different story.

I have to get him to the Vet, but it's so expensive. Probably do the
UTI tests, but might consider a blood test too if it's not expensive.
If they can't figure it out, then it's time to weigh the pro/cons of
euthanasia. So sad.

You might try putting a, "wall" on one side of his litter box.....

Or, try all three sides... (but not the entrance)
