A. Inappropriate elimination or house soiling can be a frustrating problem but with a bit of detective work on your part, there is hope. First, before deciding that this is a behavioral issue, any medical problems (diarrhea, constipation, fecal incontinence, pain on defecation, etc.) need to be ruled out and/or treated. If your cat receives a clean bill of health from your vet but is still eliminating outside the litterbox, then we need to consider that something about the box itself might be aversive to your cat. Cats can be quite finicky about their litterbox and toileting habits. Below I have listed common recommendations and cat preferences for litterbox use. Review the list and make any changes that could account for your cat's aversion to defecating in the litterbox:
* Soft, fine-grained clumping litter (vs, coarse-grained, non-clumping litter)
* 1 - 1 1/2 inch depth (especially older cats or cats with hip problems)
* Larger pans (especially for large cats) - want to get whole body inside - poop just outside the box might mean the box is too small
* Open, non-hooded
* At least one shallow side to get in and out easily
* Easy to get to - not hidden away, preferably in areas they spend time in or near - and not near appliances that make scary, unpredictable noises (washers, dryers, refrigerators)
* Scoop minimum 1X/day - preferably 2
* Clean the litterbox with soap and water and put in fresh scoopable litter at least once/month (instead of just continuously adding)
* Some cats prefer to urinate in one box and defecate in a separate box, so you may need 2 boxes even if you just have 1 cat. Multi-cat households should have 1 box/cat plus 1 extra.
