When a cat won’t poop in the litterbox anymore

Updated Dec 21, 2021

Dear Cathy,

Our six-year-old house cat stopped pooping in the litter box, but she still urinates in it. We find poop all over the house, but never urine.  She doesn’t have a favorite place to evacuate; it’s on rugs, hardwood floors – she isn’t hiding it.  We find it out in the open and it trails off.  It seems like she continues to evacuate while she walks away. We’ve been to our vet and there is nothing physically wrong. 

Nothing in the house has changed; no one new and no renovations. It’s the same litter box, same room, and same litter. Her litterbox is in a room we spend a lot of time in and she often is in there with us. Her food is in another room. We do have another cat, her sister.  We’ve had both since they were kittens and have never had any problems until recently. They get along great, playing with and grooming each other. 

So far, we have tried a new litter box, removed the top from the litterbox and did bloodwork at the vet.  We’re out of ideas.  Can you help us?

Dear Steve,

Cats don’t generally poop while they’re walking. I am not a veterinarian, but it sounds a little like fecal incontinence. Your veterinarian probably ruled that out, but if you are not sure if he or she did, please discuss this with your veterinarian. Cats should not poop while they’re walking.

If she’s healthy and squatting to poop, then we need to dig a little deeper to figure out why she suddenly won’t use the litter box. I know you went through a list of things that could cause that to happen, but let me offer a few more possibilities.

Cats are extremely sensitive to scents. Were any new scents sprayed into the air or a new air freshener located or plugged near the litter box? Did you use ammonia or citrus-smelling cleaners to clean the litter box? These scents are off putting to cats.

Sometimes, if a cat is startled near the litter box or experienced an especially difficult bowel movement (something you wouldn’t know happened), he or she will associate the litter box with that experience and will poop someplace else. My suggestion is to add a second litterbox to your home, perhaps in a more private space. Use a fine grain, unscented litter product, and fill two to three inches high. Cats like to paw and scratch to cover up their waste and often prefer a little depth to their litter. If she starts to use this second box, then you know she might have had a bad experience at the other box.

Let me know if this suggestion helps her.
