Why Is My Cat Peeing Outside the Litter Box?
House-soiling is one of the most common cat problems and often has a medical cause such as a urinary tract issue, bladder inflammation or crystals. Rule out medical causes first, then look at the box and stress.
Emergency warning
A male cat repeatedly straining in the litter box with little or no urine may have a urethral blockage. This is life-threatening within hours — go to a vet immediately.
Medical causes
- Feline idiopathic cystitis (stress-related bladder inflammation)
- Urinary crystals or stones
- Urinary tract infection
- Kidney disease, diabetes or hyperthyroidism (more urine)
- Arthritis making the box hard to climb into
Litter box fixes
- One box per cat, plus one
- Scoop daily; full clean weekly
- Unscented, fine-grained litter most cats prefer
- Large, uncovered boxes in quiet spots
- Low entry for older cats
