Is it safe to give a cat MiraLax when they are on prednisone?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 9 years and 10 months old | 12 lbs

Dewey is currently on prednisone. I’m not sure if she has pooped the past two days as one of my other cats shares litter boxes with her. Can I give Dewey MiraLax with prednisone? I gave her a 1/8 of teaspoon this morning. Did I possibly do more harm than good?

This drug can be a little tricky when giving it. Your pets complete medical history should be known before starting this laxative, due to possible complications that can ensue. Because of this, I would not continue its use without consulting with Dewey's primary care veterinarian. It is used in veterinary medicine, but it has certain requirements and cautions with use. Also it should always be dissolved and not given in powder form. As a side, Prednisolone does not have constipation as one of the possible side effects to using this medication. If she is constipated, then there is likely another underlying cause. Best of luck moving forward with your pet Dewey. Take care.
