Cat Owners: “Are You Missing The Signs?”

New Awareness Campaign Sponsored by Merck Animal Health to Help Identify the Signs of Feline Hyperthyroidism

MADISON, NJ January 12, 2015 – Merck Animal Health (known as MSD Animal Health outside the United States and Canada) is launching a new global awareness campaign designed to help cat owners recognize the signs of feline hyperthyroidism and identify if their cat may be at risk for the fatal disease. The campaign features an interactive risk-assessment quiz that asks cat owners simple questions about their cat’s body condition and behavior to help them identify if they should consult their veterinarian to test their cat for feline hyperthyroidism. 

Recent prevalence studies in many countries show that at 1 out of 10 cats aged 9 years old and older are hyperthyroid.1-4 Recent market research in Europe found that 70% of veterinarians believe that hyperthyroidism in cats is underdiagnosed because pet owners don’t recognize the signs associated with the disease.5 Veterinarians believe it is important to help cat owners recognize that, as their cat ages, they may not see the signs of feline hyperthyroidism or they may mistake changes in their cat for regular aspects of growing older. 

“We want to help cat owners to evaluate their cat’s body condition and behaviors to encourage them to visit their veterinarian if they think their cat may be at risk,” said Thierry Martine, Merck Animal Health. “If left untreated, feline hyperthyroidism is fatal. However, if caught in time, it can be well managed with medication or other treatments.” 

The most common signs of feline hyperthyroidism are weight loss and poor body condition. Other frequent signs include increased appetite, increased thirst and urination, restlessness or aggression and gastrointestinal signs.6

Feline hyperthyroidism can be diagnosed by a veterinarian using a few simple tests. If diagnosed, there are treatment options available to manage the condition. Cat owners who want more information should talk to their veterinarians.
