Few things are more frustrating for cat parents than discovering a surprise puddle or pile outside the litter box. But before you trade your slippers for rubber boots, take heart—most cases of house soiling can be managed and even reversed with a little detective work, a dash of patience, and a sprinkle of love. Let’s explore what might be going on and how to help your kitty get back on track!

Step 1: Rule Out Medical Issues

First things first: If your cat is suddenly eliminating outside the litter box, it’s time to call your vet. Urinary tract infections, kidney disease, arthritis, and even stress-related illnesses can all cause inappropriate elimination. Pain, increased urgency, or difficulty getting to or into the box may be the root of the problem.

Step 2: Evaluate the Box Setup

Cats can be very particular about their potty spots! Common litter box deal-breakers include:

• - A dirty litter box (scoop daily and clean regularly)
• - Too few boxes (have one per cat, plus one extra)
• - Unpleasant litter type or scent
• - Box that’s too small or has high sides
• - Scary or hard-to-reach locations
• - Being ambushed by another pet while using the box

Try offering a litter box buffet (different litter types and box styles) to discover your cat’s preference.  Make sure the litter box is big enough (at least 1 and ½ times the length of the cat from nose to rump), easily accessible to senior cats who may have joint pain, in a quiet location, and distributed throughout the living space so that the cat does not have to travel far to use the restroom. 

Step 3: Make the Box Irresistible

Help your cat fall back in love with the box! Keep it clean, offer privacy, and avoid placing it near noisy appliances or food dishes. If your kitty has a favorite (wrong) spot, try placing a box there temporarily and then slowly moving it to a more suitable location.  Cat Attract Litter Additive may be added to further entice your kitty to use the litter box. 

Step 4: Make the Wrong Spots Less Appealing

Use an enzymatic cleaner to remove lingering smells, then try one or more of the following:

• - Block access to the area
• - Use furniture or feeding stations to change the space's purpose
• - Add texture deterrents (like double-sided tape or a plastic carpet runner)
• - Try feline pheromone sprays and plug-ins like Feliway® to reduce stress
• 
  
• Pro Tip: Use a black light to find hidden spots of urine so you don’t miss cleaning any accident spots.  If urinary accidents have occurred on the carpet, you can dilute the enzymatic cleaner with water and inject this solution into the carpet pad. 

Step 5: Supervise, Confine, and Reward

If you're not sure which cat is the culprit, or if habits are proving hard to break, try confining your kitty to a small room with a clean litter box, food, and bedding. Gradually reintroduce freedom as they reliably use the box. Reward success with treats and praise. 

Pro Tip: If you are not sure which cat in a multi-cat household is defecating (pooping) outside the litter box, you can try grating different colors of non-toxic crayons into fine pieces with a cheese grater and mixing them in canned food (a different color for each cat).   Whichever color shows up in the poop will tell you the perpetrator. 

Final Thoughts

House soiling is a stressful challenge, but with thoughtful changes and some sleuthing, most cats can return to proper potty habits. Every cat is different—be patient, stay observant, and don’t hesitate to reach out to your veterinarian or a feline behavior expert for help. With a bit of teamwork, you and your kitty can enjoy a clean, happy home once again!
