Single-ingredient muscle support for cats – MYOS Feline Muscle Formula contains one ingredient: Fortetropin®, a patented fertilised egg yolk powder studied for its effect on muscle. A powder sprinkled onto food. Made in the USA, available in the UK at Boss Pets.

Why muscle condition matters – Cats lose muscle with age, and the muscle around a joint carries load that would otherwise pass through the joint itself. Maintaining muscle is part of keeping an older cat mobile.

How it is given – 1 to 2 grams daily, measured with the enclosed scoop, where a quarter teaspoon is 1 gram. Make sure your cat eats the full serving.

Contains egg – Fortetropin® is derived from fertilised chicken egg yolk, worth knowing if your cat has a known sensitivity.

Have weight loss investigated first – Noticeable weight or muscle loss in a cat should always be checked by a vet. Kidney disease, an overactive thyroid and diabetes are all common causes, all found on blood tests, and none of them is addressed by a supplement.

Key Features

A single ingredient – Fortetropin®, a patented fertilised egg yolk powder, and nothing else.

Supports muscle mass and condition – Studied for its effect on muscle, and relevant to cats of all life stages.

Powder format – Sprinkled onto food, with no pills or tablets to give.

1 to 2 grams daily – Measured with the enclosed scoop, where ¼ teaspoon is 1 gram.

Contains egg – Worth knowing if your cat has a known sensitivity.

Made in the USA – Available in the UK at Boss Pets, with fast delivery.

Benefits

Supports lean muscle development – Ideal for senior, recovering, or underweight cats.

Slows muscle loss (atrophy) – Beneficial for aging cats or those with reduced activity.

Promotes full-body wellness – May aid in healthy skin, coat, eyes, bones, and cognitive function.

Highly palatable – Your cat will love the taste and won’t know it’s a supplement.

How to Use

Sprinkle 1–2 grams of powder per day onto your cat’s food. Measure using the included scoop (¼ tsp = 1g). Ensure your cat consumes the full serving. Always follow your vet’s advice, especially for long-term use or specific conditions.

How It Works

Fortetropin® works by regulating protein synthesis and degradation, encouraging muscle growth while slowing the process of muscle breakdown. This natural compound harnesses the power of fertilised egg yolk to support strength and mobility without synthetic additives.

Why Choose

One ingredient – Fortetropin® and nothing else, which makes it straightforward to combine with other products.

A powder cats will take – Sprinkled over food rather than given as a tablet, which matters with cats.

Small daily amount – 1 to 2 grams a day, measured with the enclosed scoop.

Contains egg – Fortetropin® is derived from fertilised chicken egg yolk.

Have muscle loss investigated – Noticeable weight or muscle loss in a cat should always be checked by a vet, as several common conditions cause it.

FAQs

What is it used for?

Supporting muscle mass and condition in cats, particularly older cats and those coming back from a period of reduced activity.

What is Fortetropin®?

A patented ingredient derived from fertilised chicken egg yolk, studied for its effect on muscle. It is the only ingredient in this product, and it contains egg.

How much should I give?

1 to 2 grams daily, sprinkled onto food, measured with the enclosed scoop (¼ tsp = 1 g). Make sure your cat eats the full serving.

My cat is losing weight — is this what I need?

See your vet first. Weight and muscle loss in cats is commonly caused by kidney disease, an overactive thyroid or diabetes, all found on blood tests and all needing treatment. A supplement does not address any of them.

Can I give it to a kitten?

Ask your vet before giving any supplement to a growing kitten.

How long before I see a difference?

Muscle condition changes over weeks and months rather than days.

Is it safe for long-term use?

It is intended for ongoing daily use. Check with your vet about long-term use, particularly if your cat has a diagnosed condition.
