Hip Dysplasia in Cats: Signs, Causes, and How to Help
Stiff, slow, or reluctant to jump? It might be more than old age.

Stiff, slow, or reluctant to jump? It might be more than old age.

If your cat has been moving a little slower lately, hesitating before jumping, or seems stiff when they wake up, it’s easy to chalk it up to age. But sometimes it’s hip dysplasia, a joint condition where the hip socket doesn’t fit the way it should. It’s less common in cats than in dogs, but it does happen, and the right care makes a real difference. Here’s what to look for, what causes it, and how to help.
The hip is a ball-and-socket joint: the rounded top of the thigh bone (the femoral head) fits snugly into a cup-shaped socket in the pelvis. When everything lines up correctly, your cat can move freely and without pain. Hip dysplasia is what happens when that fit is off. The ball and socket develop abnormally, leading to looseness, friction, and eventually joint damage.
Over time, that ongoing wear causes inflammation and arthritis, the painful stiffening of joints that makes everyday movement harder. It’s a progressive condition, meaning it tends to get worse without management, but it’s rarely a crisis diagnosis. With the right support, most cats do well.
One of the trickiest things about hip dysplasia in cats is that they’re excellent at hiding discomfort. Cats evolved to mask pain, which means the early signs of hip dysplasia in cats can be subtle enough to miss. Here’s what to watch for:
Genetics play the biggest role. Hip dysplasia in Maine Coon cats is well-documented, with studies suggesting the condition appears in a notable portion of the breed. Persians are also at higher risk. Larger, heavier cat breeds are more prone overall because more body weight means more pressure on developing joints.
That said, genetics aren’t the only factor. Rapid growth, obesity, and previous joint injuries can all influence how the hip joint develops or deteriorates. Even a cat without a predisposed breed background can develop hip problems under the right conditions.
If your vet suspects hip dysplasia, they’ll start with a physical exam, gently moving the hips to feel for looseness, grinding, or pain. One specific test they may use is called the Ortolani sign: the vet rotates the hip joint in a particular way to detect whether the ball is slipping in and out of the socket, which signals joint laxity (looseness).
X-rays are the next step, and usually the most telling. They let the vet see exactly how the ball and socket fit together, whether there’s any joint damage, and how far along any arthritis has progressed. Sedation is typically needed to get accurate X-ray positioning, so your cat will be relaxed during the process.
Treatment depends on how severe the dysplasia is and how much it’s affecting your cat’s quality of life. Your vet will guide you, but here’s the general landscape:
When conservative management isn’t enough, surgery may be on the table. The two main options are:
Here’s one of the most practical things you can do right now, before any treatment plan is fully in place. A few simple changes around your home can take real pressure off your cat’s hips every single day.
Managing hip dysplasia over the long term adds up. Regular vet visits, prescription medications, joint supplements, and potentially an FHO or total hip replacement surgery can run into the thousands. That’s where having a pet insurance policy in place early really matters.
Lemonade pet insurance can cover hip dysplasia in cats, as long as the condition isn’t considered pre-existing at the time you enroll. That’s the key: if your cat is already showing symptoms or has already been diagnosed, it’s likely to be excluded as a pre-existing condition. But if you get coverage before any signs appear, a condition like hip dysplasia would generally be eligible for coverage.
For breeds like Maine Coons and Persians with known genetic predispositions, getting a policy in place early, ideally while your cat is still young and healthy, is worth thinking about sooner rather than later.
Hip dysplasia isn’t a condition to panic about, but it is one to take seriously. The earlier you catch the signs, the more options you have, and the more comfortable your cat’s daily life can be. If something about the way your cat is moving feels off, trust that instinct and check in with your vet. And if you have a Maine Coon, a Persian, or another larger breed, it’s worth asking your vet to assess their hips at their next routine visit, even if everything seems fine. A little attention now can go a long way, and so can having the right coverage in place before you need it.
Early signs include subtle lameness or limping, hesitation before jumping, a bunny-hop running style, and stiffness after rest. Because cats hide pain well, these signs can be easy to miss at first.
Yes. Hip dysplasia in Maine Coon cats is well-documented, and Persians are also considered higher-risk. Larger, heavier breeds tend to put more stress on developing hip joints, which raises their likelihood of developing the condition.
An FHO is a surgical procedure where the ball portion of the hip joint is removed. The surrounding muscles compensate and create a functional, pain-free joint. It’s a common and effective option for cats with severe hip dysplasia.
Yes, many cats do well with non-surgical treatment, including weight management, glucosamine and other joint supplements, pain medication prescribed by a vet, and home modifications to reduce strain on the hips.
Vets use a physical exam, sometimes including a test called the Ortolani sign to check for joint looseness, followed by X-rays to assess how the ball and socket fit together and whether arthritis has developed.
