Been wondering about Tiger I'm taking away the dry food as well to lower my cat's fiber intake, but keeping up with the Miralax and grain free wet food. I have a thought for you. I took my cat to the vets yesterday and what I thought was constipation apparently isn't. He has alot of lower lumbar and hip pain. If your kitty is having pain and associates the litter box with pain, could be why Tiger is going outside the pan. Just a thought. My cat was giving a long acting steriod for inflammation and pain and I take him back in next Thursday. An hour after the shot, he pooped three times without any problem.
