Activ Stress for Cats: Powered by Tri-Biotics + Psychobiotics

Cats experience stress differently, which is why Activ Stress was formulated specifically for the feline gut-brain connection, not simply adapted from our dog formula.

It combines Tri-Biotics: Prebiotics, Probiotics and Postbiotics with targeted Psychobiotics, feline-specific strains, trypsin digest of casein and Microbiome Assist™ to support calm behaviour, everyday stress resilience, gut health and normal immune function.

Built from what we learned developing our clinically researched canine microbiome range, Activ Stress applies the same gut-first philosophy in a formula designed specifically for cats.

The mission stays the same: support the gut, support the gut-brain connection, and help cats feel calmer from the inside out.

And because consistency matters, it comes in a highly palatable freeze-dried treat made with Australian chicken breast, sweet potato and Queensland blue pumpkin - one simple treat per day, with no powders, mixing or guesswork.

Benefits of Activ Stress for Cats

Helps cats cope better with changes in routine, new environments, travel, visitors and other common stress triggers.

Supports the feline gut-brain connection to help promote relaxation and everyday emotional wellbeing.

The Science Behind True Feline Health

At Activ Pet Health, we believe better products start with better science — and yes, we love cats just as much as dogs, my wife probably more so.

That’s why Activ Stress was developed specifically around the feline gut-brain connection, using species-specific microbiome support rather than generic formulas or strains borrowed from humans or dogs.

Our formula combines Tri-Biotics - Prebiotics, Probiotics and Postbiotics - with targeted Psychobiotics, feline-specific strains and Microbiome Assist™ to support the gut environment, calm behaviour and everyday stress resilience.

It’s the same gut-first thinking behind Activ Pet Health, now developed specifically for feline stress support.

Why 90 Days Matters

Supporting the microbiome takes consistency. Daily use helps give the gut time to adjust and establish a more stable routine, which is why we recommend using Activ Stress consistently for around 90 days.

The Story Behind Activ Stress for Cats

Cats experience stress in their own way, and their gut-brain connection is different too. That’s why Activ Stress was developed specifically for cats, using Tri-Biotics, targeted Psychobiotics, feline-specific strains and Microbiome Assist™ to support calm behaviour, emotional balance and everyday stress resilience.

It’s the same gut-first thinking behind Activ Pet Health, now developed specifically for feline stress support.

MICROBIOME ASSIST

Microbiome Assist™ is our approach to advanced Tri-Biotic support, combining Prebiotics, Probiotics and Postbiotics in a formula developed specifically for the feline microbiome.


Designed to support the gut environment and gut-brain connection, helping provide targeted microbiome support for calm behaviour and everyday stress resilience.
