Being a cat owner includes dealing with various health conditions, particularly as they age. One common condition in senior pets is arthritis, which is often regarded as just a sign that a cat is naturally starting to slow down. Technically, arthritis can affect a cat at any age, but it is most commonly seen in cats ages 6 years or older.

Let’s take a deeper look at arthritis, how it affects cats, and how you can help your cat get through it and improve their quality of life.

What Is Arthritis?

Arthritis is typically associated with the elderly, both in humans and animals. It’s also known as degenerative joint disease and occurs when cartilage on the joints starts to wear away.

Cartilage is the connective tissue between the bones. It acts as a cushion to prevent the ends of the bones from rubbing against each other. When the cartilage wears away, and the bones start to grind against each other, it can cause extreme pain.

It can also lead to further cartilage damage and the formation of new bone around the joint. This condition, known as osteoarthritis, causes stiffness and limits movement.

In cats, arthritis most commonly affects the elbows, knees, ankles, hips, and spine. Unfortunately, there is no cure, but there are treatments and medications that can help.

How Old Are Cats When They Develop Arthritis?

It is a common disease that affects cats, and a 2011 study found 61% of cats over the age of 6 had osteoarthritis in at least one joint,1 and 48% had it in more than one joint.

The study also discovered that the older the cat gets, the higher the chances of developing arthritis. But younger cats also have the potential to develop arthritis, particularly after an injury to the joint. Causes of arthritis that are not a result of aging include:

  • Lyme disease or other tick-borne diseases
  • Injury to a ligament
  • Infection
  • Immune-mediated diseases (like immune-mediated non-erosive polyarthritis)2
  • Congenital disability
  • Physical trauma (such as getting hit by a car or a fall)

What Are the Signs of Arthritis in Cats?

When a cat is injured or sick, they don’t typically show signs of illness or pain. When you start to see something wrong with your cat, the illness or injury has progressed beyond the cat’s ability to hide it.

Before you realize your cat has arthritis, you might notice that they are slowing down and not running and jumping as much as they used to.

Signs of arthritis can include:

  • Limping
  • Wasting away the muscles
  • Having swollen joints
  • Walking stiffly and limping
  • Reacting when touched on certain parts of the body
  • Having difficulty jumping up and down from furniture
  • Having an unkempt appearance due to a lack of grooming
  • Sitting or sleeping in unusual positions
  • Going outside of the litter box
  • Being more irritable than usual

Most of these clinical signs don’t occur suddenly but gradually, so they may be challenging to notice. That is why taking your cat to your vet for annual wellness checks is essential, particularly as they age.

What Are the Causes of Arthritis?

It’s not just one cause that can lead to osteoarthritis, but several factors.

  • Obesity
  • Body structure
  • Improper joint development (elbow or hip dysplasia)
  • Orthopedic surgery
  • Injury history
  • Genetics (with some breeds being more prone, like the Scottish Fold)
  • Natural wear and tear

Checklist for Arthritis in Cats

Since it can be difficult to tell when a cat has arthritis, a checklist can help you determine if you should take your cat to the vet sooner rather than later.

Occasionally, going through a simple checklist as your cat ages might help you catch arthritis in its early stages. These six questions are simple versions of the kinds of questions that a vet will ask:

  • Does your cat jump down normally?
  • Does your cat jump up normally?
  • Does your cat climb down steps or stairs normally?
  • Does your cat climb up steps or stairs normally?
  • Does your cat chase moving things like prey or toys?
  • Does your cat run normally?

You can take videos of your cat with your phone while they’re running up the stairs, jumping, and playing, which you can show your vet.

How Does the Vet Diagnose Arthritis?

The vet will start by reviewing your cat’s medical history and finish up with a physical exam. They will look for:

  • Pain in the joints
  • Noticeable joint deformity
  • Decreased range of motion
  • Fluid in the joints
  • Grating or clicking noise when the joints move
  • Joint instability

The veterinarian will also take X-rays of your cat’s bones to confirm a diagnosis and discuss treatment options.

How Do You Treat Arthritis?

  • Weight Loss – If your cat has weight issues, work with your vet to help them attain an appropriate weight. This can include a special diet and perhaps more playtime with your cat.
  • Pain Control – Medications that reduce joint swelling can help with pain. Anti-inflammatories are often used for arthritis. Other possibilities to consider include massage, laser, or physical therapy, acupuncture, and supplements that contain omega-3 fatty acids, chondroitin, and glucosamine. Hot and cold therapy can also help with arthritis pain.
  • Surgery – Surgery might be necessary if the arthritis is extreme. It doesn’t ensure that the arthritis won’t return, but it might give your cat a better quality of life. Surgery options include joint replacement, joint fusions, or removal of abnormal bony tissue that develops in joints.

What Should You Do for Your Cat at Home?

Beyond keeping your cat at a healthy weight and administering medication and supplements, you can modify your house to make it easier for your cat to navigate.

Litter Box

Cats might stop using the litter box if they find it painful to get in and out, so invest in a box with one lower side.


If your cat likes to snuggle on your couch or bed but can no longer jump high enough, invest in steps or ramps. They will make it much easier for your cat to get up and down and prevent them from accidentally injuring themselves by jumping and missing.

Appropriate Cat Bed

You can find orthopedic beds for cats with arthritis that can make sleeping more comfortable. A heated bed or pad for cats is also helpful because heat can relieve the pain. Just be careful with the heat level, and don’t ever use a human heating pad; cats have sensitive skin and are more likely to burn.

Keeping your cat comfortable and feeling secure when you are away will have them well rested and ready to play when you return. The Hepper Nest is a modern cat bed designed to meet the specific needs of cats. Its high sides offer a sense of security and the bowl shape gives support like a warm hug from their favorite person.

Same Floor

If you live in a home with multiple levels, keep everything your cat needs on one floor: their litter box, food, water, toys, etc.

Non-slip Mats and Rugs

If your tiled or laminated floors are slippery, the flooring might cause your cat to slip and fall. Invest in non-slip mats and rugs, so your cat doesn’t injure themselves.

Elevated Bowls

Elevated food and water bowls can make eating and drinking easier for your cat because they don’t have to bend down. Also, consider picking up a cat fountain to encourage your cat to drink more water. Most are tall enough that your cat can drink sitting or standing.

Observing your cat over the years will familiarize you with their body language and moods. You’ll likely be the first to notice anything unusual and pick up when something is wrong. Even if it seems insignificant, take your cat to see the vet.

Also, be proactive, keep your cat at a healthy weight, and visit your vet every year. Speak to them about any of your concerns. They can help you develop a healthy diet and exercise plan to keep your cat healthy, which can go a long way toward preventing arthritis, at least for a while.
