By Dr Duncan Houston BVSc, Ask A Vet Blog

Finding poop outside the litter box is frustrating and concerning—but it's never “just spite.” In 2025, veterinary experts recognize this behavior as a sign of medical issues, discomfort, litter-box dissatisfaction, or stress. This guide will help you understand the causes, troubleshoot effectively, and implement vet-backed strategies to reclaim that clean kitty routine. 😊

• Box number & size: Offer one more box than cats in home, at least 1.5× your cat’s length :contentReference[oaicite:9]{index=9}.
• Box location: Choose quiet, low-traffic areas away from food and appliances :contentReference[oaicite:10]{index=10}.
• Open vs. covered: Some cats dislike covered boxes; for arthritic or senior cats, low-entry open boxes may be better :contentReference[oaicite:11]{index=11}.

3. 🏡 Prevent and Redirect Accidents

• Block favored areas: Restrict access to soiled spots or use deterrents like mats or double-sided tape :contentReference[oaicite:13]{index=13}.
• Provide accessible boxes: Strategically place litter boxes near accident spots until habits improve.

4. 🧠 Recognize Stress & Behavioral Triggers

• Environmental changes: New pets, people, moves, or loud noises can trigger avoidance behavior :contentReference[oaicite:14]{index=14}.
• Social conflicts: In multi-cat homes, improve box access and reduce competition :contentReference[oaicite:15]{index=15}.
• Routine disruption: Cats prefer predictability—structured feeding, play, and elimination routines support good habits.

Supportive steps: Use pheromone diffusers, environmental enrichment (towers, toys), and positive reinforcement for correct litter use :contentReference[oaicite:16]{index=16}.
