How to choose a joint supplement for your cat: a feline vet’s checklist

There are plenty of joint supplements for pets, but relatively few have been designed specifically for cats.

Many products on the shelf were designed around dogs, then repackaged with a smaller serving for cats. Others have a long list of fashionable ingredients but very little information about where those ingredients came from, how much is included or whether the formula was built around feline physiology.

Cats metabolise many compounds differently from dogs and often show discomfort through small changes in behaviour. The evidence used to formulate a supplement should reflect those differences.

After 25 years working exclusively with cats, these are the things I check before I recommend a joint supplement.

First, make sure a supplement is the right next step

Cats are very good at hiding joint pain. Many do not present with an obvious limp. Owners are more likely to notice a gradual change in routine.

You may notice that your cat:

• hesitates before jumping;

• takes a lower route to the couch or bed;

• no longer uses a favourite windowsill;

• moves stiffly after sleep;

• grooms their lower back less often;

• struggles with a high-sided litter tray; or

• seems more irritable when picked up or touched.

These changes deserve attention, but a supplement should not replace a veterinary assessment. If a change is sudden, your cat seems painful, stops eating or their behaviour changes significantly, book a vet visit. There can be several causes of reduced movement, and your cat may need pain relief, diagnostic tests or other treatment.

Joint supplements work best as one part of a wider support plan.

1. Check that the formula was designed for cats

This is my first filter.

A cat-specific product should be formulated around feline physiology rather than scaled down from a dog or human supplement. The company should be able to explain why the ingredients and serving were chosen for cats.

“Suitable for cats and dogs” is not automatically a problem, but it should make you ask more questions. Which species was the research conducted in? Is the serving based only on body weight? Does the formula account for the way cats digest and use those ingredients?

If the answers stay vague, keep looking.

2. Look for active ingredients with a clear job

I prefer a short formula in which each ingredient has a defined role and a relevant evidence base.

The ingredients I chose for JOINT+ include:

Undenatured Type II collagen

Type II collagen is the main collagen found in cartilage. In its undenatured form, it is used to support healthy immune pathways associated with cartilage and joint comfort.

Hydrolysed collagen peptides

These are smaller, readily available collagen fragments that provide amino acids used by connective tissue. The “hydrolysed” part simply means the collagen has been broken into smaller peptides that are easier to digest.

Glycine

Glycine is an amino acid and an important building block for collagen and connective tissue. It has a complementary structural role within a joint-support formula.

New Zealand green-lipped mussel

Green-lipped mussel is a shellfish native to New Zealand. It naturally provides omega-3 fatty acids and other nutrients used to support healthy inflammatory pathways, joint comfort and mobility.

When I see green-lipped mussel on a label, I check where it was sourced, what it contributes and how it fits with the rest of the formula.

3. Ask about sourcing, quality and meaningful amounts

An ingredient name on the front of a packet tells you very little by itself.

Look for a brand that is transparent about:

• where key ingredients are sourced;

• why each ingredient is included;

• whether the ingredients are quality controlled;

• whether the amounts are based on published evidence; and

• what is not included, such as fillers, colours or inactive ingredients.

Dr Bec’s green-lipped mussel is sourced from verified, sustainable New Zealand suppliers. The formulas use human food-grade ingredients and are made in Australia.

Ingredient quality and dose carry more weight than the claims on the front of the pack.

4. Choose a format your cat can take consistently

Joint support is not a one-off treatment. It needs to fit into daily life.

If your cat will not chew a tablet, or can detect a hidden capsule from three rooms away, that format is unlikely to work for your household. A supplement that stays in the cupboard cannot support your cat.

JOINT+ is a powder designed to mix with food. For a particularly cautious cat:

1. Add a small amount to a familiar meal.

2. Mix it through thoroughly.

3. Gradually build to the serving shown on the pack.

4. Keep the routine consistent.

Most cats accept it readily. If your cat refuses it, that format may not suit your household. Dr Bec products have a 30-day money-back guarantee because no product is right for every cat.

5. Be wary of overnight promises

Good joint support is usually gradual.

Some cat owners notice a change sooner, while others need several weeks of consistent use. The first signs may be easy to miss because they look like ordinary moments:

• less hesitation before a jump;

• a smoother start after sleep;

• more interest in play;

• returning to a favourite chair; or

• grooming an area that had become difficult to reach.

Keep a short note on your phone before you start. Record the places your cat currently uses, how they manage stairs, whether they hesitate and how interested they are in play. Compare the same behaviours over time rather than relying on memory.

The aim is to help the same cat move more comfortably.

6. Look for a brand that tells you when to see your vet

A responsible supplement brand should never suggest that its product replaces veterinary care.

Your vet may recommend a combination of approaches, including:

• maintaining a healthy body weight;

• prescription pain relief;

• ramps or steps to favourite places;

• a low-sided litter tray;

• warm, supportive bedding;

• gentle, regular movement; and

• a daily joint supplement.

For many cats, the best outcome comes from several small changes working together.

If your cat takes medication, has a diagnosed health condition or uses other supplements, ask your vet before adding something new.

The short checklist

Before you buy a joint supplement for your cat, ask:

• Was this formula designed for cats?

• Are the active ingredients supported by feline evidence?

• Can the company explain what every ingredient is doing?

• Are sourcing and quality standards clear?

• Can my cat take this format every day?

• Are the expected results realistic?

• Does the brand encourage veterinary care when it is needed?

If you can answer yes to all seven, you are looking in the right direction.

Why I created JOINT+

I created JOINT+ because I could not find a joint supplement for cats that met my own checklist.

It combines undenatured Type II collagen, hydrolysed collagen peptides, glycine and verified New Zealand green-lipped mussel in a focused, cat-specific powder. It is made in Australia and designed to be added to food as part of a consistent daily routine.

JOINT+ is intended to sit alongside veterinary care. It does not replace diagnosis, pain relief or other treatment recommended by your vet.

If your cat is slowing down, hesitating before jumps or quietly giving up the places they used to love, start with a vet conversation. When daily joint support is appropriate, JOINT+ is the formula I made for them.
