Cat Joint Supplement Buyer’s Guide
Common Cat Joint Problems
One of the most common cat joint problems is osteoarthritis, a painful joint disease that gets worse over time. Aside from age- or activity-related wear-and-tear, other risk factors for developing the disease may include genetics, being overweight or obese, or previous joint injuries. When a cat develops osteoarthritis, the cartilage cushion that protects the bones and absorbs impact starts to deteriorate. This causes the bones of the joint to rub against each other, which leads to pain. You may start to notice a change in the way your cat jumps or climbs stairs, or they may be less active than usual.
“Cats with osteoarthritis are reluctant to play and move around, show…stiffness after exercise or prolonged rest, and show irritable behavior when they’re approached or touched,” explains veterinarian Dr. Jonathan Roberts.
Cats may also suffer from orthopedic conditions that can increase their risk of developing osteoarthritis, such as patellar luxation, where the kneecap “slips out” (dislocates) when the cat is walking or running, and hip dysplasia, an abnormal formation of the hip joint that causes looseness (laxity) in the cat’s joint.
If your cat has one of these conditions—or is at risk of developing one—cat joint supplements might help. “Not only can these daily supplements potentially alleviate a cat’s discomfort when they have already been diagnosed, but they can be used as a preventive measure in high-risk cases,” explains Amber LaRock, a licensed veterinary technician.
Dr. Michelle Burch, a clinical veterinarian, agrees. “Cat joint supplements can help decrease inflammation in the joint, which will reduce pain,” she says. “Supplements can also help encourage cartilage health to decrease the rate of degeneration in the joint.”
Cat Joint Supplements: Beneficial Ingredients
“Most joint supplements will have a combination of ingredients, as this allows them to work together to achieve adequate joint support,” LaRock says.
Some of the common beneficial ingredients to look for in cat joint supplements include:
- Glucosamine and chondroitin. Glucosamine is an essential chemical compound that’s found naturally in the body, but it also comes in supplement form to help the body repair and produce healthy cartilage and synovial fluid (a slippery fluid that lubricates the joints). It’s often paired with chondroitin. Together, glucosamine and chondroitin are considered the “building blocks of cartilage and help maintain healthy cartilage and slow the deterioration during osteoarthritis,” says Dr. Roberts.
- Methylsulfonylmethane (MSM). MSM is a natural source of sulfur that prevents further destruction of cartilage and decreases inflammation. It has even been shown to decrease pain and arthritis.
- Omega-3 fatty acids. Omega-3s, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are often found in fish oil and can help reduce inflammation.
- Perna canaliculus (green-lipped mussel). Green-lipped mussel extract “can provide anti-inflammatory effects resulting in mild pain relief,” Burch says. However, it might take a few weeks before you see the effects once you start giving a supplement with this ingredient.
- Creatine. Creatine improves muscle health, not the joints directly, but if your cat has muscle loss, it will put less stress on their joints.
- Avocado-Soybean Unsaponifiables (ASU). ASU is a “relatively new kid on the block, but this ingredient partially blocks the inflammatory process from starting and prevents deterioration of sensitive cells within the joint,” Roberts says.
What to Look for In Cat Joint Supplements
When it comes to shopping for cat joint supplements, there are a few things to consider.
First, joint supplements can come in a variety of forms, including chews, powders, pills, and liquids. There is no “wrong option,” as long as the ingredients are safe.
However, “cats are generally considered picky and fussy eaters,” Roberts reminds us. “For this reason, I would always recommend either a highly palatable powder or liquid supplement to place over their food. Tableting cats is always a challenge—even for professionals.”
Flavored treats might also work well, as long as your cat likes the particular flavor.
It’s also important to remember that supplements for cats are not regulated by the Food and Drug Administration or another oversight committee, Burch says. “Due to the lack of regulation, supplement labeling can be misleading or false,” she says. “I recommend using products recommended by your veterinarian or having a quality seal by the National Animal Supplement Council (NASC).”
Companies that have a NASC Quality Seal have passed an independent third-party audit and demonstrate ongoing compliance with certain criteria to ensure quality and safety standards for your cat, as well as labeling requirements.
You can also look for a product with a lot number on the packaging, because this likely means that the company has a quality control process in place.
Burch also recommends looking for products that are made by companies that have their contact details easily located on the packaging so that you can ask questions or request additional information about their research, safety, and testing company practices.
Precautions When Giving Cats Joint Supplements
Make sure you start by reading the packaging before giving a joint supplement to your cat. “While it is very difficult to overdose on feline joint supplements, it is advisable to always stick to guidelines,” says Roberts. Signs that your cat consumed too much could include vomiting, diarrhea, lack of appetite, and flatulence.
Be sure to also run the supplements (and their ingredients) by your veterinarian if your cat already takes a prescription. Some supplements could interact with their medication.
Remember too that supplements can help, but if your cat has severe osteoarthritis or chronic joint pain, your veterinarian will develop a full treatment plan that may include pain medication and other therapies to manage your cat’s condition.
