My senior cat is severely constipated and very sick. What can I do?

Updated On September 23rd, 2025

Pet's info: Cat | Ragdoll | Female | spayed | 11 lbs

My cat is 13 years old and was constipated for the first time, she's been to the vet three times in the last week, had enemas, was sent home with laxatives but she still won't pass. It's been days now, her pupils seems constantly dilated and she's breathing quite rapidly all the time. She gets up and walks but still seems lethargic. Eats a little but wont drink. Is there anything I can do for her? Is it time?

Poor Angel! This can be such a problem in older cats. You can add in some canned pumpkin (1 teaspoon a day) to help increase her fiber intake. Also, if you haven't already, I would talk to your vet about doing some abdominal x-rays. These will help the vet see how large the colon is and how much stool is present. Cats can get something called megacolon where the muscles in their colon don't work well and they get easily constipated. These cats usually need to be sedated and manually have some of the stool removed and then put on a drug called cisapride. Some cats will have to stay on this drug long term, but I have personally had good success with putting them on a food called Royal Canin GI Fiber Response and eventually getting them off cisapride and stool softeners. It is a prescription food so I would talk to your vet about it. Also, . Every cat is different and your vet will need to help guide you through this process. If your vet doesn't think she has megacolon then cisapride may not be needed but if she is REALLY backed up then she may still need to be sedated and have some feces removed to help her out. I hope this helps!

    Thanks for using Petco Pet Education Center, formerly Petcoach! I would recommend that you consider adding 1 teaspoon of canned pumpkin to her meals which can help with constipation. If no improvement, I recommend that you have her evaluated by a veterinarian for further assessment and recommendations. Best of luck!

    Thank you for submitting your question regarding Lilly. Good job on including wet food in her diet and trying to include more water for her. Increasing moisture content should help to soften the stool. If this becomes an ongoing problem for her, she should see her veterinarian. She may have a disease such as kidney problems. This can make a cat dehydrated leading to constipation. If this is not the case, she may need a prescription laxative. I hope this information helps!

    Consider talking to your vet about a stool softener, such as lactulose. This can help with dry, hard stool. Also, try increasing your cat's water intake by adding water to canned food or offering a water fountain.

    Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Gracie. I would advise that you have Gracie evaluated by your veterinarian due to her age and the fact that she is drinking less and is having problems passing stools. This could be something more serious than just getting her stools back to normal. Your veterinarian can evaluate her after getting a thorough history. They can then advise some tests fecal/blood/urine tests, and possibly some x-rays to assess the degree of constipation. Some cats have to be placed under anesthesia to relieve the impaction/obstipation of their colon. These cats commonly have what is called megacolon but we don't know that in Gracie's case. It could be something else causing it. Remember wet food has a very high water content and that would be better for getting more fluid into her at this point if you can't get her to the vet right away. You can also try Miralax or the generic over the counter to see if you can get her bowels moving again. For a cat I would give about 1/8 - 1/4 teaspoon of the Miralax mixed with the wet food. This has become a very good tool to use for pets having temporary or chronic elimination problems. Canned pumpkin also works well but I would try the Miralax first. Again, it's best to have her seen by her veterinarian due to her age and what is going on. Good luck with Gracie.
