My cat has constipation. When is it an emergency vet visit?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 7 years and 8 months old | 14 lbs

My cat has had constipation issues in the past which ultimately ended in him getting an enema. Ever since, he has been on Miralax 1/4 tea. daily AND 1/4 tea. pumpkin added to his wet food. This helped for awhile, but the past few days he hasn't pooped much. He's eating and acting normally. He gets VERY sick in the car. How do I know when it's URGENT he goes to the vet right away? The vet said I could increase his miralax dose which I did but nothing has happened yet. Help!

I usually say if there's straining in the litterbox with little to no stool produced in 24 hours, or if there are 3 days with no stool (but no straining is seen) it's time to head to the vet. The fact that he is eating normally is a good thing since appetite tends to decrease with constipation. At any time if he seems painful it is best to go to the vet. You may want to check in with your vet and see what their criteria would be for when to head in - they know more about Bug's particular case and might make different recommendations.
