Cats Behaving Badly

As a holistic vet, I’m frequently asked, “How can I deal with my cat’s bad attitude?” The problem area dubbed “feline aggression” can be complicated, upsetting and potentially hazardous for pet parents. Not only can cat bites and scratches really hurt, they can transmit diseases, too, such as cat scratch fever (yes, it is real). While most cat moms and dads prefer a purring lap-warmer, especially on cold winter nights, some felines need extra help learning how to sheathe their claws.

Unfortunately, feline aggression is not well understood or handled appropriately. An important first step in dealing with this frustrating issue is to understand the behavior. Learning why a cat lashes out can help pet parents deal with the issue patiently and properly.

In this post I’ll be covering the five basic types of aggression in cats. More...

Feline Hyperthyroidism

Since the late 1970’s, there has been a significant increase in the prevalence of feline hyperthyroidism, making it the most common feline endocrine disorder in the world. What causes hyperthyroidism, and why is it so common? Previous studies of cats in the U.S., Great Britain and New Zealand have identified a number of risk factors for the development of hyperthyroidism, including genetic predispositions, the feeding of some canned cat foods and cross-breeding. Furthermore, some veterinarians believe feline hyperthyroidism is simply an outcome of cats living longer. But, if thyroid dysfunction is symptomatic of old age, why is it not more common in dogs, or people for that matter?

Veterinarians first noticed a dramatic surge in feline hyperthyroidism in the 1980’s. This rise coincided with the prevalent use of PBDE’s as a flame retardant in many products. A chemical flame retardant used widely in carpet pads, furniture, and electronics, PBDE (or, polybrominated dephenyl ethers) were researched in a recent EPA study that suggested that these chemicals may partly explain the current epidemic. PBDE’s linger in the environment, and cats ingest the substance in both foods and by licking their fur which retains house dust laced with toxic PBDE particles. Furthermore, studies have also shown a link between hyperthyroidism and BPA in the lining of many canned cat foods. Life’s Abundance is proud to inform our consumers that the lining in our canned foods is BPA-free.

An Environmental Science & Technology study reported in 2007 looked at whether hyperthyroid cats had greater body burdens of PBDE’s, and found that all cats have high levels compared to humans, with some cats with incredibly high levels (Dye et. al, 2007). The potential link between feline hyperthyroidism and PBDE exposure may be the veritable “canary in the coal mine” when it comes to evaluating the human health impacts of PBDE’s. People in the United States have the highest PBDE levels reported worldwide, according to a 2004 study also published in Environmental Science & Technology. By gaining a more complete understanding of chronic indoor PBDE exposure and its effects on thyroid hormone levels in cats, medical researchers can better assess whether the same risk exists for people. Researchers believe that further studies need to be performed before concluding a direct link between PBDE’s and feline hyperthyroidism.

There is good news, however. It isn’t necessary to rip up your carpet and throw out your furniture as these chemicals have been or are in the process of being banned in many states. And cats still live longer, healthier lives if they live primarily indoors, and the risk of being attacked by other animals or hit by a car while roaming outside is still much greater than the risk of developing hyperthyroidism from PBDE exposure.

What can you do if your cat has already been diagnosed with hyperthyroidism? What are the symptoms? In this video, Dr. Sarah reviews the signs of hyperthyroidism and treatments available. If you suspect your kitty has hyperthyroidism, schedule an appointment with your local veterinarian.
