If you’re asking yourself, “Why won’t my cat use the litter box?” you’re not alone. Litter box avoidance is one of the most common behaviour problems in cats, and one of the most frustrating for owners. The good news? With the right approach, most litter box problems can be solved.
Why Cats Stop Using the Litter Box
1. Medical Issues
Pain or discomfort can make the litter box an unpleasant place. Common health problems include:
Urinary tract infections (UTIs)
Bladder or kidney stones
Constipation
Arthritis
2. Stress and Anxiety
Cats thrive on routine. Moving house, adding new pets, hosting guests, or even loud renovations can stress them out, leading to litter box avoidance.
3. Litter Box Setup Problems
Even healthy cats may refuse the litter box if:
It’s too small or hard to get into
It’s dirty or smells strongly of scented litter
It’s in a noisy or high-traffic area
4. Multi-Cat Household Tensions
If you have more than one cat, they may compete for litter box territory. The golden rule: one box per cat, plus one extra.
How to Solve Litter Box Problems
Visit your vet first – Rule out medical causes.
Scoop daily – A clean box is a happy box.
Add more boxes – Especially in multi-cat homes.
Test litter types – Many cats prefer unscented, fine-textured litter. Suggested litter brand: Cat’s Best
Try different box styles – Covered vs. open, high sides vs. low entry.
Reduce stress – Provide quiet hiding spots and consistent routines.
