Hello,
In my experience constipation on cats is always secondary to something else. Either old wounds, like a fractured pelvis, an underlying disease, or diet.
Has your cat had a thorough examination, bloodwork and X-rays? Have your tried different diets, supplements and fluid therapy.
I hope this helps.





Hello
I don’t know if there was supposed to be a photo with this?
Anything abnormal should be seen by a vet. I would worry about an infection or possible tumor.
