What makes our cat FMT special? It’s sourced from a group of naturally-reared cats that have been raised and nurtured for optimal health since the 1980s — that's over 40 years of careful breeding and natural living.
Our donor cats eat a consistent diet consisting of raw and organic food that matches what cats would naturally eat in the wild. This species-appropriate nutrition has been their only food source for their entire lives, creating an exceptionally healthy gut environment.
Their care has been completely holistic from birth — they've never been exposed to antibiotics, commercial cat foods, or conventional medications that could harm their delicate gut balance. They drink pure water and live in a clean, natural environment.
With this carefully curated, health-conscious donor network, our FMT products are crafted to deliver superior support for your cat’s digestive health and overall vitality—while honoring sustainability and animal welfare principles.

Why FMT for Cats?
Feline FMT (Fecal Microbiota Transplant or Microbiota Transplant Therapy (MTT)) treatment involves transferring of very healthy microbes through fecal matter from a healthy donor cat to a recipient cat's gastrointestinal tract to restore the balance of healthy gut bacteria. Here are some of the main benefits of feline FMT treatment:

Many cats suffer from vomiting, diarrhea, and inflammatory bowel disease. The pure microbiome from our naturally raised donor cats can help restore proper digestive function.

A balanced gut affects everything from immune function to energy levels. The strong, diverse microbiome from our donor cats helps support your cat's whole-body health.

Cats with digestive issues often have dull coats and skin problems. Many owners notice their cats develop softer, shinier fur after FMT treatment.

Our donor cats' pristine gut bacteria can help your cat better process and tolerate different foods, potentially reducing sensitivities.

When digestion improves, many cats experience fewer hairballs and associated problems like constipation.

FMT Vs Probiotics for Cats
Fecal microbiome treatment (FMT) transfers beneficial gut bacteria from a healthy cat donor to your cat's digestive system, restoring proper bacterial balance. The real advantage is that with FMT, your cat can actually grow these healthy bacteria within their own gut, providing ongoing protection against disease and reversing numerous symptoms. This is quite different from probiotics, which are taken to support gut health but don't establish permanent colonies - meaning they must be given daily to maintain any benefits.
The benefits of FMT over probiotics include:
Complete Microbiome
Our FMT contains thousands of beneficial bacteria from naturally raised, healthy cats that have never been exposed to antibiotics or commercial foods. Most probiotics only have a few strains.
Long-lasting Benefits
FMT can actually establish permanent colonies in your cat's digestive system. The diverse, strong microbiome from our donor cats helps create lasting change, unlike probiotics that typically wash out quickly
Naturally Sourced
Our FMT comes directly from exceptionally healthy cats that have been naturally raised for generations - not from a laboratory. This means your cat receives the exact microbiome composition that healthy cats naturally have.
FAQ
To help you feel comfortable with FMT treatment for your dog, we have included answers to frequently asked questions:
What is FMT treatment?
FMT stands for Fecal Microbiota Transplant. It takes the healthy gut bacteria from our naturally raised donor cats (raised organically since the 1980s) and transfers it to your cat's digestive system. This helps restore balance to your cat's gut and can improve many health issues.
What are the potential benefits associated with FMT for cats?
FMT can help cats with digestive issues, food sensitivities, skin problems, and overall health. The pure, strong microbiome from our holistically raised donor cats can help restore your cat's natural gut balance, potentially improving energy, coat quality, and immune function.
How are our Legacy Biome Healthy Gut Restore Capsules for cats made?
We carefully collect samples from our special donor cats that have been naturally raised for generations on a raw, organic diet. We then filter and purify this material to concentrate all the beneficial bacteria. The final product is gently dried and put into special capsules designed to reach your cat's intestines intact.
How does my cat take the capsules? Can I crush or mix with food?
For best results, give the capsule whole to your cat. Many cat owners find success by using pill pockets or a pill giver tool. Don't crush the capsules or mix with food - the special coating helps the capsule reach the right part of your cat's digestive system intact.
How long can I store my cat's FMT Capsules?
The capsules stay fresh for up to 2 years when stored in your refrigerator. No need to freeze them.
Can I get reimbursed by pet insurance for my cat's FMT capsules?
Good news! Many cat owners with pet insurance like Trupanion have received up to 90% reimbursement when the FMT is prescribed by their veterinarian. We recommend checking with your pet insurance provider about your specific coverage.
