Cat constipation is more than just an uncomfortable situation for your furry friend—it can lead to serious health complications if not addressed. Many cat owners find themselves searching, “What to give a cat for constipation?” to ensure their pet stays healthy and happy. In this article, I’ll explore the causes and risks of constipation in cats, including its potential to result in megacolon and kidney issues. I’ll also offer practical tips and tricks to help relieve your cat’s constipation, including using remedies like Miralax, pumpkin, and lactulose. Gyula was chronically constipated and I used them all!
Why Constipation in Cats Is a Serious Issue
Constipation occurs when your cat struggles to pass stools or has infrequent bowel movements. While occasional constipation may not be cause for alarm, chronic constipation can lead to severe health problems.
The Risk of Megacolon
One significant complication of prolonged constipation is megacolon. This condition occurs when the colon becomes severely enlarged and loses its ability to contract properly, making it nearly impossible for your cat to pass stool without medical intervention. Once a cat develops megacolon, treatment often involves long-term medication, dietary changes, or even surgery depending on the severity.
Gyula developed megacolon when I was away on a vacation in 2023 however he didn't have a severe case. His colon became very stretched out and it did retract although not quite back to it's normal shape. He was able to pass stools normally but he would also drop little pieces of stool as he walked and moved around. It was a constant clean up game and I would need to wash his behind frequently which he was not fond of.
How Constipation Affects the Kidneys
Constipation doesn’t just impact the digestive system; it can also strain your cat’s kidneys. When waste isn’t eliminated regularly, toxins that should be excreted can build up in the bloodstream, potentially leading to kidney damage or exacerbating existing kidney issues. Ensuring your cat’s digestive system is functioning properly is crucial for overall health.
What to Give a Cat for Constipation
If your cat is constipated, several remedies can help get things moving again. Here are some tried-and-true solutions but please talk to your vet before starting any regime:
1. Miralax
Miralax (polyethylene glycol) is a gentle, over-the-counter laxative that works by drawing water into the colon, softening stool, and making it easier to pass. It’s tasteless and can be mixed into your cat’s food or water. There is an orange flavored one which you want to avoid but feel free to buy the generic version. It's the same thing and so much cheaper. Gyula had Miralax daily and if I could give you one tip that made it so much better for him, it would be to mix the Miralax with water first so that it dissolves before adding it to food. Otherwise the Miralax will suck the water out of the food. I would make a slurry that would last a few days so that I didn't have to always make it and it worked out wonderfully! Before starting on Miralax, consult your veterinarian for the appropriate dosage based on your cat’s weight and condition.
2. Pumpkin
Canned pumpkin (plain, unsweetened) is a natural fiber supplement that can help regulate your cat’s digestive system. A teaspoon or two added to their meals can provide the extra fiber needed to promote healthy bowel movements. Most cats tolerate pumpkin well and even enjoy its taste. There are also so many wet food pouches, treats and supplements that contain pumpkin or
you can also make your own treats. Check out my Salmon and Pumpkin Cat Treats recipe that your cats will love!
3. Lactulose
Lactulose is a prescription medication that acts as a stool softener and helps stimulate bowel movements. Like Miralax, it works by drawing water into the colon but is often prescribed for more severe cases of constipation. Your veterinarian can guide you on how to administer lactulose and adjust the dosage as needed.
Gyula also had this but my vet cautioned me from using it too often. It's not something that you want to use on a daily basis for a long period of time is what my vet told me.
Tips and Tricks to Help a Constipated Cat
In addition to these remedies, there are several steps you can take to help prevent or alleviate constipation in your cat:

Hydration is Key: Ensure your cat has access to fresh water at all times. Dehydration is a common cause of constipation, as it makes the stool harder and more difficult to pass. You can also add a teaspoon or so to their meals so they get a bit more water into them.
Switch to Wet Food: Wet cat food contains more moisture than dry kibble, which can help keep your cat’s digestive system hydrated.
Encourage Exercise: Regular activity helps stimulate the digestive system. Play with your cat daily to keep them active and engaged.
Provide a Clean Litter Box: Cats are notoriously picky about their bathroom habits. A clean, accessible litter box encourages regular use and can prevent them from holding it in.
When to See a Vet
While pumpkin and extra water in their food can often relieve mild constipation, it’s essential to consult your veterinarian if:
Your cat hasn’t had a bowel movement in more than two days.
You notice vomiting, lethargy, or a loss of appetite.
Your cat shows signs of pain or discomfort when using the litter box.
These could be signs of a more serious condition, such as megacolon or a blockage, requiring immediate medical attention.
Conclusion
By taking proactive steps to address your cat’s digestive health, you can help them stay comfortable and avoid complications.
If your cat is experiencing persistent constipation, don’t hesitate to consult your veterinarian for personalized advice and treatment options. A little care and attention can go a long way in keeping your feline friend healthy and happy.
