While I've never had to deal with anything of your scale, I do totally sympathize with you. My Jack has Mega Colon and sometimes I'm having to clean poop from places other than the litterbox but not daily. I know he can't help it, but it is a frustrating problem. I can't imagine how difficult it is for you to be dealing with the urinating also, and with 3 cats to boot.

I can't say as I blame you one bit for feeling like you do about the situation. I'm sure you're doing more and enduring more than tons of people out there would do.

If I found myself in that same situation I'd probably have to balance out what's good for the cats vs whats good for me, the other cats, my house, and the impression I'm making as a pet owner on other people.

I don't envy your situation, and I pray that you find a solution that works soon. If you do have to rehome the cats I wouldn't blame you as you have done more than thousands of cat owners would do already and are giving them the best chance they have. Is it possible that the particular combination of those 3 cats is the problem? Maybe having to resort to rehoming all 3 wouldn't be necessary, just one or two of them? Just a thought.

Good luck.
