The Scoop on Cat Poop


Cat Poop Problem: Constipation continued...

There are a number of things that can cause cats to become constipated, including:

  • Over-grooming, which leads to extra hair in the digestive tract
  • Kidney problems
  • Feline megacolon
  • Some type of obstruction, including string or bones
  • Diets that are low in fiber
  • Colon abnormalities such as strictures or tumors
  • Spinal problems or pain

To help ease your cat’s constipation, your veterinarian may suggest increasing the fiber in the diet, such as by adding canned pumpkin to your cat’s regular food. Or your veterinarian might recommend switching to a diet that is very easily digested, thereby lessening the amount of poop in your cat’s digestive tract.

Encouraging your cat to get more exercise and drink more water may also help poop move through her system more readily.

The chart below may help you to identify the cause of your cat’s poop problems:
