One of the more common ailments to afflict senior cats is arthritis. Clinical studies have shown that 22-64% of all cats and 90% of cats older than twelve years old have radiographic (x-ray) signs of arthritis. Cats most commonly develop arthritis in their hips, elbows, knees, ankles, and spine.
Arthritis causes pain and loss of movement of the joints. The word arthritis literally means joint inflammation (arth=joint, ritis=inflammation). Inflammation is a reaction of the body that causes swelling, redness, pain, and loss of motion in an affected area. Normally, inflammation is the way the body responds to an injury or to the presence of disease agents, such as viruses or bacteria. During this reaction, many cells of the body's defense system - called the immune system - rush to the injured area to wipe out the cause of the problem, clean up damaged cells, and repair tissues that have been hurt. Once the battle is won, the inflammation normally goes away and the area becomes healthy again.
In many forms of arthritis, the inflammation does not go away as it should. Instead, it becomes part of the problem, damaging healthy tissues of the body. This may result in more inflammation and more damage - a continuing cycle. The damage that occurs can change the bones and other tissues of the joints, sometimes affecting their shape and making movement hard and painful.
As with most illnesses and injuries in cats, the symptoms of arthritis can bey very subtle and easily missed especially if they are gradual in onset. Many of them are dismissed as simply being signs of "old age" and not necessarily indicative of an actual, treatable (or at least manageable) ailment. Symptoms can include:
unusual sleep patterns;
eliminating outside the litter box;
hiding;
avoiding interaction with people or other pets in the home;
dislike of being stroked or brushed;
decreased grooming, reluctance or inability to jump as high as they once could or to go up stairs;
reluctance to jump down or landing ungracefully/with difficulty;
decrease or change in play;
stiff gait or lameness.
Diagnosing arthritis involves a thorough exam that may reveal pain, crepitus, and/or swelling in the joints. Pain can be difficult to interpret in cats during an exam because they are not in their familiar environment. To help with this, we rely on your observations of the cat's behavior at home as well as diagnostic tools as radiographs (x-rays). Radiographs can show changes in the bony structures of the joints, which do indicate developing arthritis. However, there can be cartilage changes that cannot be seen on radiographs.
Although treatment may not turn your senior cat into an agile and active kitten, it will relieve pain and distress and enable your cat to do normal activities. Treating arthritis is tackled with a three-pronged approach: nutrition, medication and environmental changes.
Nutrition: Just as with humans, being overweight can exacerbate symptoms and pain associated with arthritis. If your cat is on the heavier side, we will work with you to help her lose some of those extra ounces. We can calculate calories needed and monitor weight loss with regular progress exams. Additionally, there are prescription diet formulas specifically designed to help with mobility issues in older cats. Finally, we may recommend fatty acid supplements that many help reduce inflammation.
Medications: Most medications used for arthritis in cats are not approved for use in cats by the FDA and are "off-label". This is due to the cost of the research to prove the safety and efficacy in cats. The medications, however, have been used extensively in cats by veterinarians and can be used safely if used at proper doses and with proper monitoring, including regular medical progress exams, blood panels, and communication with your veterinarian.
There are a variety of medication types available to help your cat:
Glucosamine/condroitin promotes the health of the cartilage and joint fluid. Adquean, delivered by subcutaneous injection, is a polysulfate gylcosaminoglycan which also helps cartilage and joint fluid. Stronger medications include NSAIDS (Non-steroidal Anti-inflammatory Drugs), which control inflammation in the joints providing pain relief. NSAIDS can cause gastrointestinal upset and damage to the kidneys, although the side effects are rare with low doses. Analgesics or steroids might also be part of your cat's arthritis therapy depending on various factors.
Many cats with arthritis benefit from multiple medications and supplements. By using various types of medications, we can keep the doses of each lower to minimize side effects. All medication treatments require regular monitoring by your veterinarian through progress exams.
Environmental modifications: In order to improve your arthritic cat's quality of life around the home, here a few suggestions for easy modifications to accommodate her. There are many litter boxes out on the market now that have lower sides, or a least a low entry side, making it easier for her to get into the box and reducing the risks of eliminating outside of it. You can also mound the litter to one side to help her position herself more comfortably when defecating. You might also consider adding additional litter boxes around the house, especially if you live in a multi-story house, so she doesn't have to walk as far to reach one.
Because access to heights is important to most cats, consider adding ramps or steps to help her get to her favorite places. There are many manufacturers of such products, specifically for older cats, or you can do a simple rearrangement of the furniture for her. Make sure she has easy access to food and water. If you feed her on a counter, add steps for her, or start feeding her on a lower plane, or on the floor.
Arthritis is a lifelong disease, and one that is likely to progress over time. The sooner it can be diagnosed and treatment begun, the more comfortable your cat will be.
Midnight is an eight and a half year old domestic short hair cat. She first came into the clinic nine months ago because she was straining to urinate and defecate. I examined her and found that she was constipated and obese. We want cats to be a healthy 5/9 on our body condition score scale. Midnight was an 8/9. Her bladder was too small to obtain a urine sample, but I suspected a urinary tract infection due to her symptoms. We gave her an enema and started antibiotics and medication to soften her stool. We also advised her owner to start feeding canned food and started her on a prescription diet food to start weight loss and relieve her constipation.
Two weeks later at her progress exam, Midnight had improved and was urinating and defecating better. However, a urinalysis showed that there was still blood in her urine so we ran more tests. Her bladder and kidneys appeared normal on an ultrasound and a urine culture ruled out bacterial infection. Since no underlying cause could be found, I diagnosed her with "cystitis" which is inflammation of the bladder. In many cases, we do not know the cause of the cystitis but it can be caused and/or made worse by stress. Stress in a cat's life can be very subtle and can be related to their environment, other animals, their diet, or painful medical conditions.
I prescribed Metacam for Midnight to help ease the inflammation and discomfort in her bladder. Metacam is a non-steroidal anti-inflammatory medication. As with any medication, repeated and long-term use may cause some side effects. If we make sure we use proper dosages and the cat is monitored well, Metacam relieves discomfort in many cats with cystitis and arthritis.
Midnight immediately started feeling much better. She was much more active. Her owner said that she had noticed stiffness in Midnight's hind end previously, but she was now moving much better.
At her progress exam a month later, Midnight was still doing very well. She was urinating and defecating normally. She no longer needed stool softeners. Her diet was doing well and she had lost almost a pound by this point. However, her urinalysis showed that she still had blood in her urine indicating that her cystitis was not fully resolved.
In order to try to improve this, we started Adequan injections to help the bladder and the likely arthritis. Adequan is polysulfated glycosaminoglycans; these are normal components of joints and the bladder wall. We give it as an injection under the skin - weekly or bi-weekly - then fewer injections as the cat improves.
Midnight is currently given Adequan injections once monthly and Metacam every fourth day and continues to do well. She has lost almost two pounds and is active and feeling well. We needed to switch her prescription food to a low calorie food with high protein rather than high fiber. This has produced more regular bowel movements for her but still helped with her continued weight loss.
Nearing nine years old, Midnight is now classified as a senior cat. Like human senior citizens, it is common to see multiple problems in senior cats. Keeping a healthy weight and feeding quality cat food helps all aspects of their health. But even trim senior cats can be plagued with troublesome and intersecting problems. Many times we have to prescribe multiple medications to address the various problems and make sure we are treating them as well as possible.

As we mentioned in our senior wellness blog, many of the diseases and conditions that commonly develop in senior cats are more easily managed when they are caught in their early stages. This helps maintain or even improve your older cat's quality of life.
In this blog, we will explain in a little more detail what exactly the tests we run tell us about your cat's health.
Many of the same technologies and medical diagnostic testing that help humans live longer, healthier lives are also available to your cat. Even a few standard tests allow us to gather a wealth of information about the well-being and health of your cat. These tests become increasingly important as your cat continues to age.
The most common lab test we run in our clinic is a combination blood panel consisting of a complete blood count and blood chemistry. A Complete Blood Count (CBC) is a series of tests that evaluate the number of cells in circulation in the blood. White blood cells, WBC, help fight infection and inflammation and can increase with cancer. Red blood cells, RBC, carry oxygen to the tissues. Platelets allow clotting of the blood and are another indication of the health of the bone marrow. Overall, the CBC tests for anemia, infection, inflammation and the health of blood cells and the bone marrow.
A blood chemistry panel is performed to get an initial overview of the health and function of body organs. This panel surveys many of the organ systems of the body to make sure they are working properly. Our chemistry test checks the following organ functions: liver, kidney, pancreas, muscle, bone, thyroid and electrolytes.
For many conditions, such as chronic renal disease and diabetes mellitus, a urinalysis should also be run to provide a complete picture of organ function. For example, in verifying renal disease, the specific gravity - or concentration - of urine is a key diagnostic tool in addition to the blood chemistry numbers. In diagnosing diabetes, glucose levels in the urine are examined.
Finally, we recommend radiographs (x-rays), first to establish a baseline at a younger age, and then regularly to monitor any changes or developments. Cats do develop arthritis, but as with many illnesses, they hide their discomfort and it's not always readily apparent until the condition becomes severe. There may be subtle signs, such as taking extra steps to get places, jumping from floor to stool to bed instead of straight from floor to bed, or refraining from jumping at all. Arthritis pain can be managed with a variety of different treatments, including a specialized diet.
Ultimately, the tests performed are designed to ensure the best quality and longevity of life possible for your cat.
September is National Senior Health Care Month and we thought this would be a great opportunity to discuss the senior health of your cat. Advances in veterinary medicine and knowledge mean that cats are living longer lives. Not that long ago, a 15-year-old cat was a remarkable survivor, but these days that cat still has several good years of life left.
So at what age is a cat considered a "senior"? According to the American Animal Hospital Association's wellness guidelines, a cat is considered to be "mature" or middle-aged at just 7-10 years of age. While that may seem early to be labeled mature, many age equivalency charts match 7 years old in a cat to mid- to late-40's in a human. A senior cat is between 11 and 14, and their geriatric, or "golden years", start at 15+.
Just as with humans, as cats get older, wellness visits become more important. As cats age, they are at risk for a number of illnesses and conditions. Most of these are more easily managed when caught early. Regular physicals and diagnostic lab work are essential to keep your senior kitty in the best health possible for a long as possible.
Starting in their mature years, we'll start looking for age-related changes. A full physical exam every six months is key to maintaining optimal health. We also recommend full lab work every other year, which includes a complete blood count, blood chemistry panel, electrolytes, thyroid and urinalysis. We will take your kitty's blood pressure during her exam to make sure no problems are developing there. We also like to establish a baseline on x-rays of the chest and abdomen so any changes are more easily recognized. We also discuss your cat's changing diet needs as well as any changes in behavior or routine that you have noticed.
Once your cat reaches her golden years, we will look more closely at lab tests and behaviors, anticipating changes as she continues to age. We perform tests more frequently, running full lab work every year and taking x-rays every other year, because we know that your cat is more vulnerable at this stage in her life.
The goal of senior care is simple. We want to help you maintain the highest quality of life for your cat and thereby enhance the bond that we all share. Together we can make the senior years the most rewarding years for you and your cat to have with each other.
See our Life Stages Health Care Recommendations page on our website for specific details on wellness at all stages of your cat's life.
