Recognize the signs of unintended weight loss and learn how Mirataz® may help

Your cat’s weight loss could be caused by a variety of issues

A change in your cat’s appetite and unintended weight loss doesn’t always have a simple answer. It could be from non–disease-related stress, like a change in where they eat.1 It could be a reaction to psychological stress, like the disappearance of another pet.2 Or it could be the beginning of a serious disease, like hyperthyroidism, chronic kidney disease, or inflammatory bowel disease.3


Prolonged inadequate nutrition may be more detrimental to your cat than the underlying cause of their weight loss.

Do not use Mirataz in cats with a known hypersensitivity to mirtazapine or any of the excipients or in cats treated with monoamine oxidase inhibitors (MAOIs). For additional important safety information and product label click here.

You can help identify the early signs of weight loss at home

As you interact with your feline friend, observe their eating habits and take the time to note any changes in their body composition.

Take notice of changes in eating habits, including:

  • Interest in food

  • Amount eaten

  • Time to finish

When petting your cat, check for:

  • Ribs or bony protrusions

  • Lumps or bumps

  • Tender spots

If your cat is losing weight, it could be a sign of a more serious underlying disease. It’s important to talk to your veterinarian immediately about changes in your cat’s eating habits or weight.

Step 3:
Using your gloved finger, gently rub ribbon of ointment on inside pinna of the cat’s ear spreading it evenly over the surface. Dispose of used gloves after each application. If contact with your skin occurs wash thoroughly with soap and warm water.

After application, care should be taken that people or other animals in the household do not come in contact with the treated cat for 2 hours because mirtazapine can be absorbed transdermally and orally.

Alternate the daily application of Mirataz between the left and right inner pinna of your cat’s ears. Do not administer into the external ear canal. If desired, the inner pinna of your cat’s ear may be cleaned by gently wiping with a dry tissue or cloth immediately prior to the next scheduled dose. If a dose is missed, apply Mirataz the following day and resume daily dosing.

Mirataz was safe and well tolerated in clinical studies

In clinical studies, Mirataz was well tolerated and used in cats with unintended weight loss associated with a variety of underlying conditions.

What you should know upon discontinuing treatment with Mirataz

Upon discontinuation of Mirataz, it is important to monitor your cat’s food intake. Your cat’s food intake may lessen after discontinuation of Mirataz. If food intake diminishes dramatically (>75%) for several days or if your cat stops eating for more than 48 hours, contact your veterinarian.
