Overview
Read the full profile
Classify first: squatting with large volume on horizontal surfaces is a urination problem; standing sprays on vertical surfaces with tail quiver are marking. Then rule out medicine: UTIs, cystitis, pre-blockage signs, and arthritic pain all cause soiling, so urinalysis precedes behavior work, and unproductive male squatting is an emergency.
Fix the environment: N+1 boxes scooped twice daily, the accepted litter type, quiet non-trap locations; enzyme-clean soiled spots and repurpose them with bowls or scratchers. Resource conflict in multi-cat homes and stray cats outside windows drive marking, so block sightlines and add resources together.
Manage behavior: marking tracks stress, so fix routines, add play, and neuter intact cats for a marked reduction, with pheromone diffusers as support. Review logs weekly and involve a veterinary behaviorist when stuck; punishment and crating only deepen anxiety-driven soiling.

Owner questions
How do I tell spraying from inappropriate urination?
Squatting with a large volume suggests urination; standing and spraying a small amount on vertical surfaces suggests marking. Both can have medical or stress causes, so start with a urinalysis.
