We can all agree that our cats deserve the best in life. Whether that’s by supplying top-shelf litter, toys that maximize entertainment, or feeding them a balanced diet, we’re always looking for ways to further their longevity. We’ve been told plenty about our gut health and microbiomes, but what about that of our cats? While giving your cat a tiny spoonful of Greek yogurt every once in a while is a great start, it turns out our cats can benefit from probiotics in the long term just as much as us.

What exactly are probiotics and why does my cat need them, you may be asking? Well, according to veterinarian Annette Louviere, “Probiotics are live microorganisms, often referred to as ‘good bacteria,’ who aid in bodily functions ranging from digestion to immune health and can even influence mood.” When the immune system senses these microbes in the gut, it launches a response. As for the latter question, Louviere notes, “Including probiotics in a cat’s diet can help add to the number of friendly microorganisms in their gut, of which there are trillions, ideally preventing an imbalance of good vs bad bacteria from occurring.”

When it comes to using probiotics, it’s best to take a preventative approach. “While there are different kinds of probiotics which can be used for certain situations, generally speaking they promote a balanced gut environment, so it’s best to be proactive with probiotics,” says Louviere. Not only do probiotics keep your cat’s gut microorganisms balanced, they also aid your cat’s digestion, energy, and metabolism, as well as boost their natural immune defenses. That’s why it’s so important to take your cat’s microflora into consideration while they’re healthy.
