What Is Cat Constipation?
Cat constipation is a short-term problem. If your cat continues to be constipated, it can become obstipation (painful defecation) or even megacolon, which is the advanced stage of chronic cat constipation that is often nonresponsive to medical management.
Always take your cat to the vet if they are straining in the litter box. The underlying cause could possibly be serious or deadly if untreated.
Symptoms of Cat Constipation
Little to no fecal production while attempting to poop
Frequent visits to the litter box
Decreased interest in interacting with family
Causes of Cat Constipation
Litter Box Issues
Sometimes cat constipation starts with a litter box issue: maybe the box isn’t cleaned frequently enough or isn’t easy to access. Or the litter box could be associated with pain while attempting to poop, or with something that’s scary to a cat, like the washing machine buzzer going off.
In these cases, your cat not wanting to go can quickly become not being able to go. To help your constipated cat, examine your litter box and its surroundings, and consider:
Moving it to a quiet location with no noises or activity that would be scary to your cat
Moving it away from your cat’s food, water, and bed
Cleaning it more often to reduce smells
Switching to a low-sided box that is easier to access
Not Drinking Enough
Cat constipation could also be caused by not drinking enough water. Your cat’s reluctance to drink might be related to an underlying health concern such as mobility issues, mouth pain, or digestive discomfort. Take them to the vet to rule out any of these issues.
Your cat might also be reacting to an issue with their water dish, such as stagnant or dirty water, or even the type of bowl. Always rule out medical issues first, especially when it comes to dehydration. Then you can also think about:
Using a cat water fountain with flowing water that mimics a stream or river
Trying water bowls made out of other materials, like glass, ceramic, plastic, or metal
Cleaning the water bowl more often
Many diseases, both acute (short-term) and chronic, can lead to constipation in cats. These include kidney disease, diabetes, and hyperthyroidism. All cases of straining in the litter box should be evaluated by a veterinarian, because each of these illnesses can become very serious or even deadly if left untreated.
A toy or other nonfood item can obstruct the intestines, preventing the passage of poop. This is
Refusing to lie down
Fever or low body temperature
The inability to urinate is also an emergency for your cat; take them in to see a vet as quickly as possible to get a proper diagnosis and treatment.
Not Enough Exercise
Inactivity can also lead to constipation. You should aim for at least 10-15 minutes of activity interactive
Cat trees provide opportunities for climbing and exploration
Scratching posts allow cats to express the instinct to scratch
Toys that mimic prey animals can attract a cat’s attention
Smart toys that move on their own motivate hunting and chasing
Catnip makes all of these activities more fun for your cat
How Vets Diagnose Cat Constipation
Providing a full history is very important because straining in the litter box can also be a symptom of lower urinary issues and diarrhea.
After getting your cat’s history, your veterinarian will perform a physical exam. In constipated cats, a vet can often feel the hard stool, but not always.
Next, your veterinarian will recommend X-rays to evaluate the extent of constipation to determine the best initial treatment for your cat. Bloodwork is often required to assess underlying diseases that may predispose your cat to constipation.
Treatment for Cat Constipation
The first step in treatment is to remove the obstructing feces, which sometimes requires administration of fluids or an enema at the clinic. Never give an enema to your cat at home, as human enemas are not safe for cats.
If the constipation is moderate or severe, your cat will need to be sedated for the enema or deobstipation (manual removal of feces).
The next step is to determine the underlying cause of your cat’s constipation and address it. You may need to make changes in your cat’s environment, like moving the litter boxes, cleaning the water bowl or litter boxes more often, or trying a cat water fountain or a different type of water bowl.
The vet may also recommend switching your cat to low- or high-fiber food and adding medication specifically for constipation.
But more often, treating any underlying disease, such as kidney disease or arthritis, is the most important treatment to prevent a recurrence.
Recovery and Management of Cat Constipation
Follow the instructions provided by your veterinarian. Often the food changes or medications will need to be continued for life. Just because your cat is feeling better doesn’t mean you can stop treatment.
Hang a calendar on the wall near the litter box to keep track of your cat’s poop schedule. This will help you be proactive at the first sign of a problem.
