Finding a surprise on the carpet instead of in the litter box? If your cat has recently changed their bathroom habits, you’re likely feeling frustrated and confused. You’re not alone—this is one of the most frequent challenges cat owners encounter. The silver lining? There’s usually a clear reason behind the behavior, and most cases can be fixed.
We turned to our trusted veterinary professionals to get expert answers to your biggest litter box questions, from health concerns to behavior tips, so you can help your cat get back to using the box with confidence.
Q: My cat has started having accidents outside the litter box. What should I do first?
Vet Tip: Rule out illness before assuming it’s a behavioral problem. Many cats stop using the litter box because of pain or discomfort. Urinary tract infections, kidney conditions, or arthritis can make using the box unpleasant. Schedule a vet visit and consider a urine test to check for these issues.
Q: What medical problems commonly cause litter box issues?
Vet Tip: These are the conditions we most often see when cats avoid their box:
- Urinary tract infections
- Feline lower urinary tract disease
- Kidney problems
- Diabetes
- Gastrointestinal issues like constipation or diarrhea
- Arthritis
If your cat is straining, meowing in discomfort, or using the box frequently with little success, seek veterinary help right away—those symptoms could signal a serious issue.
Q: My cat is physically fine. What else should I consider?
Vet Tip: After ruling out medical causes, turn your attention to possible stressors or environmental triggers. Cats are highly sensitive and can be thrown off by:
- A box that isn’t scooped regularly
- Switching litter brands or textures
- Moving the box to a new spot
- Household changes like moving, new pets, or guests
- Tension with another cat
- Loud or startling sounds near the box
Even seemingly minor changes can cause your cat to avoid their litter box.
Q: How many litter boxes should be in my home?
Vet Tip: Follow this rule of thumb: one litter box per cat, plus an additional one. So if you have two cats, you should have three boxes. This helps prevent conflict and gives your pets options.
Q: Does it matter what kind of litter I use?
Vet Tip: Yes. Cats tend to prefer unscented, clumping litter with a soft feel under their paws. Scented or crystal varieties can be a turnoff. If you need to change the type of litter, do it gradually by mixing it with the old brand over a few days.
Q: Where’s the best place to put the litter boxes?
Vet Tip: Choose calm, low-traffic areas that are still easy to access. Avoid isolating the box or placing it next to noisy appliances like washing machines. Older cats especially need convenient access with no stairs or barriers.
Q: What kind of litter box do cats like best?
Vet Tip: Most cats prefer uncovered boxes—they offer better air circulation and visibility. Enclosed boxes can trap odors and may feel unsafe to your cat. Be sure the box is large enough: it should measure at least 1.5 times the length of your cat from nose to tail.
Q: How often should I be cleaning the litter box?
Vet Tip: Scoop waste daily and fully clean the box weekly using unscented soap and warm water. Cats are very clean animals, and a dirty litter box is one of the top reasons they stop using it.
Q: I’ve tried everything—what’s next if my cat still won’t use the box?
Vet Tip: Start tracking when and where accidents occur. This can help you spot patterns or triggers. Consider using a calming diffuser or a litter attractant. And don’t hesitate to call your vet if the issue persists—acting early often leads to better outcomes.
The Bottom Line:
Litter box issues might feel overwhelming, but they’re typically solvable with the right approach. Whether the problem stems from health, stress, or setup, there’s a solution out there. Most importantly, your cat isn’t acting out on purpose—they’re trying to tell you something.
