Answer-first

Is my cat spraying or avoiding the litter box — and what do I do?

Look at the surface and the posture: spraying is small amounts on VERTICAL surfaces from a standing, tail-quivering cat; litter-box avoidance is squatting on HORIZONTAL surfaces. They have different fixes — but both start with a vet visit to rule out medical causes.Fact

Cornell's first step for any house-soiling is a thorough physical exam. Urinary disease can look exactly like a behavior problem — this page only applies AFTER your vet has cleared health causes.

Applies to: Cats already examined by a vet for house-soiling, or owners preparing that visit. A cat straining, crying in the box, or passing little/no urine is an EMERGENCY, not a behavior question.

Steps

Tell them apartFact
  • Spraying: vertical surfaces (walls, chair backs), standing posture, lifted quivering tail, small amounts, consistent spots
  • Avoidance: squatting, larger amounts, soft surfaces (carpet, beds, laundry) or cool hard ones (tile, tub)
  • Take a phone video if unsure — it's the single most useful thing to show your vet
If it's marking (after the vet visit)Fact
  • Intact cat? Neutering/spaying is the highest-yield step — hormones drive much spraying
  • Find the trigger: a new cat indoors, or outside cats visible at windows/doors
  • Clean marked spots thoroughly; synthetic cheek-pheromone products can help
  • More enrichment and predictable routine lower the stress that fuels marking
If it's avoidanceProfessional guidance
  • Audit the boxes: number, size, location, litter type, cleanliness — see our litter-box pages
  • Never punish — it adds the stress that keeps the cycle going
  • Clean accidents with an enzymatic cleaner so the spot stops advertising itself

Normal vs keep-watching

Normal: Zero house-soiling. Occasional scratching around the box or perching on the edge is quirk, not soiling.

Keep watching: Where (vertical/horizontal), how much, how often, which cat (multi-cat: video or brief separation), and what changed in the home the week it started.

When to contact a vet. Before ANY behavior plan: a vet exam (Cornell's explicit first step). Straining, blood, crying in the box, or a male cat producing no urine = emergency now. This page never diagnoses urinary disease.

What changes this answer

  • Intact vs neutered
  • New cat or outdoor cats visible (marking trigger)
  • Recent move/renovation (stress-driven)
  • Multi-cat home (identify the soiler first)

Common mistakes

  • Skipping the vet and buying deterrents
  • Punishing or rubbing the cat's nose in it
  • Cleaning with ammonia products (smells like urine to cats)
  • Treating spraying and avoidance with the same fix
