I'm am sorry you kitty is going outside the box often. I have a cat that still has his claws, and occasionally he'll go outside his box on the bathmat in the bathroom. He does this when he deems the box not sanitary enough for him. Some cats will not go in the box after they have peed in it. So even if you have already scooped it that day, he might go pee, then need to poop again (some cats go twice a day or more) and he might not want to poop with a pee clump in there. I know his litterbox problems stem from when he was a kitten... I was not yet married to hubby and he and the stepkids NEVER cleaned the box on the days I was nt here. So poor Allen ALWAYS had a disgusting dirty box. He developed a pickiness about his box. How can I fault him for something my family did to him? I take my pennence and scoop his boxes at least once a day. I am constantly adding fresh litter.

Though it does seem suspicious that your cat's litterbox problems began after the declaw. He might go outside the box because he associates the pain with the litter. It hurts a lot less to scratch and bury poop into carpet than it does to do the same in gritty, rocky litter. I have had a cat with complications from declaw. Its not as uncommon as people think. Like yourself, and now Calliesmom, most people have no clue that their cat's litterbox problems can be directly linked to the declaw. Imagine if all the people with declawed cats who have litterbox problems realized this... we might finally have some concrete proof that declawing leads to behavioral issues.
