I apologize for calling you he,I am actually a she but catspaw66 is correct that I was asking because it can definitely be a reason why cats avoid the box. In giving an answer to a question like this, it is important info since at least some of the time, when a cat is declawed, that is the entire reason they don't use the box and pain management can then be the solution. I am against declawing unless it is necessary for the health of the cat, which is extremely rare.
