Do you think you know the five most common cat diseases? The findings in Banfield Pet Hospital’s State of Pet Health 2012 Report may surprise you.

The report captured and analyzed data from nearly 430,000 cats in 43 states over a period of five years. The driving force behind the study was a commitment to preventive care and early diagnosis. In addition to collecting medical data, the report also identified pet owner perceptions. For this part of the report, Banfield polled more than 1,000 cat owners in the United States.

The report also captured date from more than 2 million dogs. This discrepancy in cat vs. dog numbers highlights the prevalent trend that dogs get far more attention when it comes to medical and health studies than cats do. According to pet journalist Steve Dale, for every dollar devoted to cat health research, five to ten dollars are devoted to feline research.

The Banfield report found that the five most common cat diseases are obesity, heart disease, kidney disease, thyroid disease and arthritis.


The 5 Common Cat Diseases

1. Obesity

The findings are disturbing: since 2007, obesity in cats has increased 90 percent, and yet, 69% of cat owners believe that their cat is just the right weight. Obesity can lead to serious health problems, including diabetes, heart and respiratory problems, joint disease, and a compromised immune system.

2. Heart disease

Heart disease is often called the silent killer, and nowhere is this more true than for cats. Because the physical signs may not be visible in early stages of the disease, many cats go undiagnosed until the disease has progressed. According to the report, at least 3 in 4 cat owners are not aware that vomiting, dental disease and weight loss can be associated with heart disease, and more than half (54%) of cat owners are not aware that aging can also be associated with heart disease.

3. Kidney disease

The prevalence of kidney disease has increased by 15% since 2007. According to the report, At least 3 in 5 cat owners are not aware that diarrhea, vomiting, lethargy or weight loss can be associated with kidney disease. Kidney disease is a progressive and chronic condition, and early diagnosis is critical for successful management.

4. Thyroid disease

Hyperthyroidism is most commonly seen in senior cats. If left untreated, it can result in heart and kidney failure. 4 in 5 cat owners are not aware that changes in a cat’s coat or unusual urination habits can be highly visible sign associated with hyperthyroidism, and less than half of cat owners (45%) realize that changes in appetite can also be a sign of the condition.

5. Arthritis

The prevalence of arthritis has increased 67% in cats over the past five years. It is unclear to me (and not addressed in the report) whether this dramatic increase is due to cats living longer, or to cat guardians being more aware that cats get arthritis, too. I believe that arthritis has been underdiagnosed in cats because cats are masters at masking pain. The report shows a clear link between arthritis and obesity: 37% of arthritic cats were also overweight – a connection that 2 out of 3 cat owners are not aware of.

It is Banfield’s hope, and I echo this, that reports like this one will help educate cat owners and veterinarians about the chronic diseases that affect cats. It is my hope that someday, cats won’t be treated as second-class citizens when it comes to studies and research. This report is a good start.

I know that Conscious Cat readers are better educated than the average cat guardian. However, even I was surprised by some of the report’s findings, and I’m curious: which of these surprised you the most?

7 Comments on 5 Common Cat Diseases Identified by the State of Pet Health Report

  1. I am not surprised to find these diseases common in cats. Either I have been unlucky or cats are plagued with health issues as I have only had one cat out of 7 that was healthy until she reached 18 years of age. Most of my cats die at a young age. One of them died of lung cancer at 4 yrs of age and we don’t smoke. One died of Irritable Bowel Disease at about 6 yrs of age. I currently have a Ragdoll that decides she won’t eat for a period of time….we’ve had all kinds of tests done and they can’t find out what is wrong. My cats are totally indoor cats and I feed them no-grain food and am currently trying to feed them raw food.

  2. Thanks for sharing. I am several days late reading my favorite blogs but I am a little surprised that there is few comment on this post.
    I know humans are busy and don’t always have the time to read these reports but it is important to have at least an idea of the symptoms or signs of a health issue to be able to recognize them. Posts like yours are hence very important too, my human and I think.
    So thank you. I’ll be sharing your post on my Facebook page, if you don’t mind.

    P.S.: my human just downloaded the report and she says 30 pages is not much to read!

  3. I had 2 cats with hyperthyroidism (one which also had heart disease and lived 4 years with both issues and ended up dieing of mouth cancer at 17!), lost one at 8 to kidney failiure (foster cat we had for 2 months), and am currently battling obesity with my 30 lb cat. We adopted him in 2005 at that weight and he’s never been below 25 lbs. I’ve had him tested medically for everything under the sun, but he just is unable to shed the weight. We’ve tried every diet, evey food–I wish he would eat a raw diet but he wont touch it. My 14 year old Persian has early kidney issues and signs of arthritis. It’s tough watching them age, but I’ll do whatever necessary to keep them healthy and comfy!
