The Question
“Dear Dr. Paola,
My (senior) cat Meeshu gets constipated from time to time, and I give her a small amount of Miralax. Yes, I know about Lax-a-tone, but she won’t have anything to do with it—whether I put it on her paw or mix it in her food. My question is, how much Miralax should I give her? She’s 19 years old and doesn’t weigh much. Thanks!”

Quick Info about Meeshu
Congratulations on the incredible care you’ve given Meeshu! At 19 years old, she’s surpassed the average cat’s lifespan, which truly reflects your dedication and love.
Constipation in senior cats, like Meeshu, often results from issues such as dehydration, arthritis making it hard for her to posture, or age-related slowing of her digestive system. Think of her gastrointestinal tract like an older car engine, it needs a little extra care and the right “fuel” to keep things running smoothly. While Miralax is commonly used to manage constipation in cats, I can’t safely recommend a dosage, since we don’t have a direct doctor-patient relationship. A veterinarian who knows her health history is the best person to determine the safest and most effective approach, and with senior cats, this tailored care is especially important.
In the meantime, there are steps you can take to support her digestion. Hydration is key, much like keeping oil in that engine. Try offering multiple water stations, adding low-sodium broth to her meals, or focusing on wet food to boost her water intake. Introducing a small amount of plain canned pumpkin (without additives) is like adding fiber to her system, helping things move more efficiently. Just be sure to introduce any changes gradually to avoid upsetting her stomach.
You’re doing an incredible job, and Meeshu is so lucky to have you championing her health and happiness in her golden years!
