SUSTAIN®
for Cats

SUSTAIN® for Cats is a probiotic supplement designed to support long-term digestive and immune health in cats. A cat’s digestive tract is home to trillions of microorganisms, collectively known as the gut microbiota.
SUSTAIN® for Cats was the UK's first veterinary probiotic, combining a strain of live "good" bacteria with a prebiotic that feeds them, plus beta-glucans to help support normal immune function and microbial fermentation solubles (MFS). Together they help maintain a healthy balance of the gut microbiota - the trillions of beneficial bacteria that play a role in digestion, immunity and overall wellbeing.
The unique SUSTAIN® formulation means the product can be beneficial in a variety of different situations and is designed for long term use. For sudden or short-term digestive upset, your veterinarian may recommend a different product, such as PROMAX®.
SUSTAIN® for Cats is available in a palatable powder, in individual sachets, for easy feeding. It is designed to be mixed in with food.
Pack Size: SUSTAIN® for Cats is available in packs of 30 individual daily sachets.
Information on Gut Health
The digestive system does much more than break down food. It is responsible for absorbing nutrients and water, and maintaining an important barrier between the contents of the intestine and the rest of the body. The digestive tract also contains a complex community of bacteria and other microorganisms called the gut microbiota or gut microbiome. A healthy intestinal microbiota contributes to normal digestion and metabolism, production of certain vitamins and other beneficial substances and maintenance of the intestinal barrier. There are many reasons your pet may experience digestive upset or gastrointestinal tract imbalance. They may have eaten something unusual, picked up an infection, experienced stress, such as when kenneled, or may have a sensitive or irritated gastrointestinal tract. We would always recommend speaking to your vet practice for further advice if you notice: • Vomiting • Soft faeces • Blood or mucous in the faeces • Changes to faeces colour or frequency • Changes to appetite • Lethargy • Bloating • Flatulence
How can SUSTAIN® help my pet ?
SUSTAIN® for Cats contains multiple ingredients to support a healthy digestive tract. The formulation contains a probiotic species, which are live microorganisms that help support a balanced population of microbiota within the digestive tract when supplied in appropriate amounts. This microbiota has many functions in the body, including helping reduce bad bacteria, maintaining the balance of the good bacteria, and supporting healthy digestion. SUSTAIN® for Cats also contains additional ingredients like prebiotic, beta-glucan and Microbial Fermentation Solubles (MFS) that provide nutritional support for the intestinal lining and normal immune function, which can also support healthy skin. SUSTAIN® can help your pet feel happier and healthier.
Why does my vet recommend SUSTAIN® for Cats ?
Probiotic supplements for cats can differ significantly in the bacterial species and strains they contain and whether they include prebiotics, beta-glucans, MFS or other supportive nutrients. SUSTAIN® for Cats has a comprehensive multi-ingredient formulation: • Enterococcus faecium DSM 10663/NCIMB 10415 - a specifically identified probiotic strain used to support a healthy balance of intestinal bacteria. Providing the strain identification is important because the characteristics associated with one probiotic strain cannot automatically be applied to every strain within the same bacterial species. • Microbial Fermentaion Solubles - MFS are are inactivated microorganisms and their by-products that help support the immune system and maintain healthy gut bacteria. • Inulin - a prebiotic fibre that provides nourishment for beneficial bacteria already living within the digestive tract. • Beta-glucan - supports the normal function of the immune system with related benefits like skin health. • L-Threonine - an essential amino acid that supports the production of the gastrointestinal protective mucus lining. • B vitamins - contribute to normal energy metabolism and support the function of intestinal and immune cells. SUSTAIN® for Cats was developed as a veterinary probiotic formulation for long-term digestive and immune support. There are lots of different supplements available, however it is important to trust your veterinary surgeon’s advice on which one is right for your pet and why. At VetPlus, animals deserve the best. This is why we always produce the best products for the pet, from the best possible ingredients in our state-of-the-art UK facility. As a result, SUSTAIN® is used by vets in many countries globally.
How does SUSTAIN® for Cats taste?
SUSTAIN® contains a tasty hydrolysed chicken flavouring, making it very palatable for cats. The powder should be mixed with your cat’s normal food. The daily amount may be given in one meal or divided between meals. A small amount of lukewarm water can be added to help mix the powder through dry food.
