A CONSTIPATED PET EXHIBITS INFREQUENT OR DIFFICULT EVACUATION OF THE STOOL:
The feces are usually hard and dry.
There are many causes of constipation in pets. Some are not serious while others can be life threatening. Correct treatment depends on identifying the cause of your pets constipation. Constipation is most often caused by dietary or environmental factors.
Fiber in the diet is important for normal defecation. A pet food with high fat and gravy levels may also be deficient in fiber. Substances such as hair, bones, or other indigestible foreign matter will mix with the stool and cause constipation. Hairballs in cats are very common.
Changes can affect your cats routine, such as removal of the litter box (or changing the type of litter), a hospital/boarding kennel stay, or lack of exercise can also cause problems.
OTHER CAUSES OF CONSTIPATION:
Pelvic bone fractures
Rectal lesions, infections, or tumors
Prostate gland disease
Spinal cord problems
