Defecation issues

by Andria

I have an older cat who has either IBD or small cell carcinoma in his intestines. Given his age we did not do a biopsy since we were told the treatment would be similar--starting with prednisolone. The only symptom is defecation outside the box! At first it was "running poops"--the kitty seemed to need to run to defecate. For a while prednisolone has helped; then we put him on venison food and that helped for about 3 weeks but now he is defecating outside the box again. He is 15. He urinates in his box just fine. He has two boxes but sometimes defecates on our bed or near our bed. I am at wit's end! He seems fine otherwise; eats well, plays, etc. Thank you


Unfortunately many cats react to stress by urinating or defecating to express discomfort with a situation. It can be a houseguest over the holidays, or numerous other things that are causing a change in its routine.

In his case it could be having to take medication or even a physical discomfort that his condition is causing. You could try moving one of the litter boxes into the bedroom at night to see if the behavior changes.

Animals can't tell us what is wrong and to communicate there is a problem, they often resort to behaviors that will get our attention.

I suggest you talk to your vet about a medication to reduce his stress and see there is improvement.

Defecating outside the box.
by: Solomon's mom

My Solly is having very similar problems to the one above. Tonight he goes for an ultrasound. He's 14. He will pee in my shower if I"m not careful. He used to run to poop under my bed. I finally removed the carpet and keep the door closed. Now he runs to get on the stairs and poops there. Squishy, nasty smelling poops. I've picked him up and put him in the box when he starts, but he stops going and then goes again on the floor. There is only one box he will pee in and that isn't every time. I have pee pads around the boxes for when he misses. He just refuses to put himself far enough in the box to pee in it. I think some of it is stress related as he has lost all the fur on his tummy, some on his back feet and thinning behind the ears. Two other cats in the house. I"m hoping tonight will give some answers. Otherwise, he is his usual self.

Update on my cat NEW
by: Anonymous

Well, we switched him to rabbit protein food mixed with a bit of proplan and all of a sudden he seems much better. I was able to reduce his prednisolone dose. So I still don't really know what is going on but at least for the last couple of weeks he is much better and is using his box. Our vet has warned me that his physical disease does wax and wane, but that stress makes it worse. Sigh! Thank you so much for posting this. I would be so interested to hear if others have cats going through anything similar!!
