How long can a cat go without pooping? It's been 24 hours which is unusual for my cat but I don't want to rush her to the vet if I'm being paranoid.

A cat can go up to 48 hours without pooping, meaning anything past 48 hrs is a cause for concern, especially if you see your pet straining to defecate and nothing coming out. Ideally every pet should have a bowel movement daily, however there can be some slight variations here depending on the GI transit time and diet. I would monitor for signs of straining and also vomiting, lethargy or lack of appetite which means that kitty should be seen for constipation/obstipation. There are also medications and supplements available through your vet (i.e. Laxatone or Lactulose) that can help keep the GI track moving along if this becomes a chronic issue. Also fiber supplementation can be discussed with your vet.

    Yes, cats should have a bowel movement 1-3 times a day. any cat who has not pooped in 48 hours needs to be examined. Here is a link about constipation: https://www.petcoach.co/article/the-big-no-go-constipation-in-cats-101/ Have Star examined today. He may need a stool softener and fluids to help him have a bowel movement. I hope this helps and please feel free to post any additional questions.

    Thanks for using Petco Pet Education Center, formerly Petcoach! Longer than 36-48 hours would be considered unusual. If you are concerned about constipation, you can add 1 teaspoon of canned pumpkin to his meals which may help. Good luck and have a good night!
