Probiotics for Cats: What are they and what are the benefits?

Probiotics are hot right now with kombuchas and kefirs a plenty. Substantial studies have and are currently being conducted on the impact for humans with evidence showing links to multiple conditions such as allergy, pancreatitis and obesity as well as brain health. To date relatively little research has been conducted on the benefits of probiotics for cats (and dogs) but the recent surge in interest for humans should see this change to benefit our pets and our own health. From our own experience with our pets, we strongly believe that good health begins in the gut for cats, dogs and humans alike, and probiotics can be helpful tools to keep the gut in check. 

Read on to understand the benefits of adding probiotics for cats.

What are probiotics?

Probiotics, not to be confused with prebiotics, are live bacteria and yeasts which maintain the balance of microflora in the gut. Prebiotics feed probiotics promoting their growth or activity. 

Benefits of probiotics for cats

When your cat suffers with an illness, or has medical treatment for a condition, the natural balance of their gut can become disrupted. You may experience bouts of diarrhoea and sickness. Probiotics will often be prescribed post problems like this to help restore your cat’s gut to its natural balance. 

Daily use of probiotics helps to support a healthy gut microbiota which helps keep your kitty happy and healthy in a number of ways. Here are some of the benefits of probiotics for cats…

Management of acute and stress diarrhoea 

Let’s face it in the pet world, sh*t matters! One of the most recent studies on the benefits of probiotics for cats and dogs shows changes in stool quality, with firmer and fewer stools for both cats and dogs. In addition to improving stool quality, when added to the diets of dogs, there was a notable increase in the concentration of the IgA antibody, which functions to protect against intestinal pathogens. Clinical trials on cats with IBD have also shown improved stool quality. 

Immune booster

Your cat’s immune system is the first line of defence when it comes to fighting off infections and bacteria – just like yours is for you. And most of your cat’s immune system lies in the gut. A study of 12 cats with the FHV-1 (Feline Herpevirus) infection were administered either a probiotic or a placebo with their food. Those that received the probiotic showed a statistically significant difference in reduced levels of conjunctivitis. Through boosting the immune system and fighting off pathogens, probiotics are thought to also help defend against allergies. 

Aids digestion

It all happens in the gut, and through keeping your gut healthy, probiotics aid digestion, helping to breakdown food and absorb nutrients. Probiotics can help to settle sensitive stomachs and help regulate bowel movements, reducing transit time and improving stool consistency. 

Weight management

The gut microbiota differs among obese kitties versus their healthier counterparts.  While probiotics won’t reduce your kitty’s weight alone, they can work wonders in conjunction with a healthy diet and regular exercise, to keep your cats gut healthy and ensure they absorb all essential nutrients from their food. Probiotics can also boost your kitty’s energy levels, encouraging them to get out and about more helping burn off some of those excessive calories. 

Can I give my cat human probiotics?

We know human toothpaste is toxic for our pets and that cats cannot eat cheese, but a probiotic is a probiotic right? Not quite, not all probiotics are the same and will impact differently. Similarly, our digestive system is very different to a cat’s digestive system, which differs again to that of a dog. Most vets agree that giving your cat human probiotics is unlikely to cause any harm but it’s unlikely to do any good either, so stick to a probiotic that’s specifically designed for cats. 

What are the best probiotics for cats?

Enteroccocus faecium is the probiotic strain that has been tested to demonstrate the above benefits in cats (and dogs). It’s important that probiotics are live so steer clear from any wet cat foods that claim to have probiotics as these will likely be killed during the cooking process.
