My cat that I’ve had for over a year, has refused to poop in his litter box for the last couple months. First thing I did was take him to vet, she said he was perfectly healthy. So we changed litter, many times. No help. He likes to go RIGHT outside the box, on the hardwood. Nothing really changed in the house to cause it, and although he’s a bigger cat, he was fine using a smaller box for the longest time. So we got him a big box. Not the biggest but pretty big. Our other cat that is longer and lanky has 0 problems. I have run out of stuff to try and we live in rentals right now, I NEED this to stop! Thank you
