Litter box avoidance guidance underscores medical-first approach

PetMD has refreshed a practical client-facing explainer on why cats stop using the litter box, highlighting nine common setup and management mistakes, from the wrong litter type and poor box hygiene to inadequate box numbers, noisy locations, and boxes that are too small or hard to access. The article, updated April 28, 2023, was written by Lorie Huston, DVM, and reviewed by Sandra C. Mitchell, DVM, DABVP. Its central message is that sudden litter box avoidance should first trigger a veterinary workup, because medical issues, pain, stress, and environmental mismatch can all drive the behavior.

Why it matters: For veterinary professionals, the piece reinforces guidance already reflected in feline practice resources: house-soiling is one of the most common behavior complaints in cats, can strain the human-animal bond, and may signal urgent disease, including lower urinary tract problems. Current feline guidance supports core recommendations echoed in the article, including one box per cat plus one extra, daily scooping, larger boxes, easy access for senior cats, and quiet placement away from stressors.

What to watch: Expect continued emphasis on pairing medical rule-outs with environmental history-taking as newer research further refines litter, box size, and box-style preferences in cats. (sciencedirect.com)
