My cat is vomiting, straining to poop, passing mucus. What's wrong?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 8 lbs

My cat hasn't been able to poop, is only getting out a clear mucus, and has been vomiting too. No changes in diet either. I had her at my vet but he said all her vitals were good and he thought she may have eaten something but passed it since she seemed to be feeling better so he gave her a steroid shot and sent us home. That was yesterday and today she's sick again and running to the box every several minutes to try to poop but no luck still. What could be wrong?

Hello sorry to hear about Sophie. There could be a many causes for her slow bowel movements. The most common may be in association with dehydration. This could either be because she doesnt have access to adequate amounts of water, she may also have kidney disease, or she may have a primary problem with her GI tract such as megacolon. You should contact your veterinarian and let him know Sophie continues to have the same clinical signs. If he deems it appropriate, they may recommend obtaining a blood and urine sample to test her kidneys, and obtain x-rays to assess how much stool she may have. Other causes for her constipation may include some kind of colitis where they may have an urge to go to the bathroom but dont actually have any stools to pass. This could be brought on by several things such as parasites, bacteria, and autoimmune diseases. Best of luck and hope this helps.
