The Best Joint Supplements for Senior Cats

As cats grow older, it is common for them to become a little less active, less keen to jump, or a bit slower getting up after a nap. While some changes can be part of normal ageing, stiffness and reduced mobility may also be linked to joint wear and tear. This is why many owners start looking into joint supplements for senior cats.

Joint supplements can be a helpful part of supporting comfort and mobility in ageing cats, particularly when used alongside veterinary advice, a healthy weight, and sensible changes at home. In this article, we explain how joint supplements may help, what ingredients to look for, and when it is important to speak to your veterinary surgeon.

This article is intended for general guidance only and should not replace professional veterinary advice. If your pet is unwell or showing concerning symptoms, please contact your veterinary surgeon.

Why joint support matters in older cats

Many senior cats develop osteoarthritis, a condition where the joints become worn and inflamed over time. This can lead to pain, stiffness, and changes in behaviour. Cats are very good at hiding discomfort, so signs of joint problems are often subtle.

You might notice your older cat:

• Jumping less often or avoiding high surfaces
• Sleeping more and playing less
• Hesitating before using stairs
• Becoming stiff after resting
• Struggling to groom properly, especially around the back or hips
• Missing the litter tray because climbing in is uncomfortable
• Becoming quieter, grumpier, or less social than usual

If you are seeing these signs, it is worth booking a check-up with your vet. Not every mobility change is caused by arthritis. Senior cats can also develop other conditions, such as weight loss, muscle weakness, or underlying illness, which need proper assessment.

Can joint supplements help senior cats?

Joint supplements are not a cure for arthritis, but they may help to support the health of cartilage, joints, and surrounding tissues. Some cats appear more comfortable or mobile when supplements are used consistently over time. They are often used as part of a wider long-term plan, rather than as a quick fix.

For some cats, supplements may be recommended early, especially if there are mild signs of stiffness. In other cases, they may be used alongside prescription pain relief or other treatments. If your cat has already been diagnosed with arthritis, your vet can advise whether a supplement is suitable and what to expect.

Ingredients often found in joint supplements for cats

There are several ingredients commonly used in feline joint supplements. Different products may contain one or more of these, and response can vary from one cat to another.

Glucosamine

Glucosamine is one of the best-known joint support ingredients. It is a natural building block of cartilage, the smooth tissue that helps joints move comfortably. In supplement form, it may help support cartilage health and joint function over time.

Chondroitin

Chondroitin is often paired with glucosamine. It helps cartilage retain water and maintain its cushioning effect within the joint. Together, these ingredients are commonly used in long-term joint care products.

Omega-3 fatty acids

Omega-3 fatty acids, especially those from fish oils, may help support the body’s natural anti-inflammatory processes. In some older cats, they can be a useful part of overall joint and skin support. If your cat has other age-related needs, you may also find suitable options in our cat skin and coat and cat vitamins ranges.

Green-lipped mussel

This marine ingredient is included in some joint supplements because it contains omega-3 fatty acids and other compounds linked with joint support. Some owners prefer products containing green-lipped mussel as part of a broader supplement blend.

MSM

MSM stands for methylsulfonylmethane. It is used in some pet supplements to support connective tissues and general joint health. Evidence is still developing, but it is a common ingredient in multi-support formulas.

Hyaluronic acid and collagen

These ingredients may be included in some advanced joint products. They are often linked with supporting joint fluid, cartilage function, and connective tissue strength.

What makes a good joint supplement for senior cats?

The best joint supplement for your cat will depend on their age, symptoms, preferences, and any other health issues they may have. In general, it is sensible to look for:

• Ingredients with recognised use in joint support, such as glucosamine, chondroitin, or omega-3s
• A product designed specifically for cats
• Clear dosing instructions based on your cat’s weight
• A form your cat will actually accept, such as a chew, capsule, powder, or liquid
• A reputable supplier offering genuine veterinary and pet healthcare products

At Vetscriptions, we stock a range of trusted pet healthcare products, including our own brand premium supplements, to help owners make practical choices for ongoing pet wellbeing.

How to give joint supplements to a cat

Cats can be particular about taste and texture, so ease of use matters. Some supplements come as powders that can be mixed with food, while others are liquids, capsules, or soft chews.

To improve acceptance:

• Introduce the supplement gradually if the product instructions allow
• Mix it into a small amount of favourite wet food first
• Offer it at a time when your cat is calm and hungry
• Be consistent, as joint supplements often need several weeks of regular use before any benefit may be noticed

Always follow the manufacturer’s instructions and do not give human joint supplements unless your vet has specifically advised this. Some human products may contain ingredients that are unsuitable for cats.

Joint supplements are only one part of the picture

Even the best supplement works best as part of a full approach to senior cat care. If your cat has stiff joints, there are several other steps that may help support comfort at home.

Keep your cat at a healthy weight

Extra weight places more strain on the joints. If your older cat is overweight, gradual weight management under veterinary guidance can make a real difference to mobility and comfort.

Make home life easier

Simple changes around the house can help older cats stay confident and comfortable:

• Provide low-sided litter trays
• Use ramps or steps to favourite resting places
• Place food, water, and litter in easy-to-reach areas
• Offer warm, supportive beds in quiet spots
• Use non-slip mats on slippery floors

Speak to your vet about pain relief

If your cat has arthritis, supplements alone may not be enough. Some cats need prescription pain relief to stay comfortable. If this is the case, your vet will recommend the safest option based on your cat’s age and overall health. If you have been given a prescription, you can find more information on how to order a prescription medicine and visit our cat prescription products section.

When to contact your veterinary surgeon

It is important to arrange a veterinary check if your cat:

• Suddenly becomes lame or unable to jump
• Cries out when touched or moved
• Stops eating or drinking normally
• Seems unusually withdrawn or irritable
• Has difficulty using the litter tray
• Shows signs of pain despite using a supplement

Older cats often have more than one health issue at the same time. For example, kidney disease, dental pain, thyroid problems, or heart disease can also affect behaviour and activity levels. A proper examination helps make sure your cat gets the right support.

Choosing trusted products for your cat

When shopping for joint care or other health products, it is worth choosing a reliable UK supplier. At Vetscriptions, we are founded and run by vets, and we focus on helping owners access genuine pet medications and healthcare products at affordable prices.

If you are unsure which products may be suitable for your cat, you can browse our cat collection or get in touch through our contact page. If your cat is on regular prescribed treatment, our prescription FAQs may also be helpful.

Conclusion

Joint supplements can be a useful way to support mobility and comfort in senior cats, especially when chosen carefully and used consistently. Ingredients such as glucosamine, chondroitin, and omega-3 fatty acids are commonly included in feline joint products and may play a supportive role in long-term joint care. However, supplements are not a substitute for a veterinary diagnosis or proper pain management where needed.

If your older cat seems less active, reluctant to jump, or uncomfortable moving around, it is always best to speak to your veterinary surgeon. Early support can make a real difference to quality of life, and small changes at home can help your cat stay comfortable for longer.
