I'm sorry to hear about your cat. What kind of canned food do you feed? Does he eat anything else (table scraps? treats?) How old is he? Has he had any bloodwork done at the vet's office? Is his urine same as always (ex/ more, less, stronger or weaker smelling, sticky, etc?)

How long has this gone on?

Customer: replied 7 years ago.
This has been going on for about 6 months and he only eats Friskies canned food no scraps . I have used vasoline and pediatric glycerin suppositories to try to help him but he goes back right after using them.
Expert:  ChristineLVT replied 7 years ago.

I would start by comparing the Friskies with other foods in the store with a higher fiber content. This on top of supplements like cottage cheese or canned pumpkin can help, as well as laxatone, which is made for hairballs but is actually an oil based product which helps move the GI tract contents along faster. The stool is staying in the intestines too long, which is why it is hardening up and turning so dark. Higher fiber is the first step. Laxatone or adding some mineral or vegetable oil to the food is another step.

There could also be an underlying reason besides just constipation, and with your cat drinking a lot of water and yet still having a dry intestinal content, it is something to consider. Things that dehydrate the body like diabetes, thyroid problems, kidney dysfunction, or other endocrine or metabolic issues can cause the body to pull more water into the cells and organs to be utilized, taking away from excess water in the intestinal tract, which softens the stool. If the above advice isn't working, I would then try having a general blood profile run by the vet to check these. Your vet could also give you prescriptions then like lactulose (another oil based product that draws water into the Gi tract) and/or cisapride, which is a drug that helps the intestines contract and push the stool out faster.

I hope your cat is back to normal soon, and wish you both the best of luck. Let me know if I can help further,

Christine

  • My oldest male cat had a seizure this evening. This site was the first place I could think of to go after the seizure had passed. Dr. Lucy was fantastic and she was spot on! Debbie USA
  • I must tell you I found this site by accident and was amazed when I asked a question of the Veteranians online. I wish I could have found it sooner it could have made such a difference in the outcome of my pet's surgery. However, I am passing along the information to my sister-in-law (a cat-rescue person who is also a nurse), and perhaps it will help someone else who may experience the same problem. The doctor who answered my question was amazing, and while it didn't come it time to change the outcome of my situation, it is reassuring to know the caliber of Vets/Doctors that you have at JustAnswer. Thank you for being there. Alice H. Jacksonville, Fl.
  • Wonderful service, prompt, efficient, and accurate. Couldn't have asked for more. I cannot thank you enough for your help. Mary C. Freshfield, Liverpool, UK
