A solution to support feline emotional balance.
Stylla Calmness contains ingredients known to support relaxation in cats, which may help during situations that commonly cause behavioural changes. The formula combines targeted actives selected for their role in promoting emotional balance without causing drowsiness. They work with your cat's natural physiology, supporting neurotransmitter function that contributes to both immediate and long-term wellbeing while maintaining normal alertness.
L-Tryptophan
A precursor to serotonin, it stabilizes mood and reduces anxiety in cats, contributing to overall calmness.
Alpha-casozepine
Derived from milk proteins, it interacts with GABA receptors in the brain to produce a calming effect similar to naturally occurring substances, without unwanted side effects.

L-Tryptophan

Benefits and why it matters
Benefits and why it matters
L-Tryptophan is a naturally occurring amino acid that plays a vital role in the production of serotonin, a key neurotransmitter often called the "happiness hormone".
Think of serotonin as a natural calming signal in your cat's brain. When L-Tryptophan is included in their diet, it helps their body produce more serotonin. This can lead to:
- A more balanced mood: by supporting serotonin levels, L-Tryptophan can help reduce feelings of stress and anxiety.
- Improved response to stress: when faced with new situations or changes in their environment, a cat with healthy serotonin levels may feel less overwhelmed.
What the science shows
What the science shows
The scientific understanding of its role and promising findings in related areas offer encouraging insights:
- Reduced Stress Markers: A commercial diet containing L-Tryptophan in cats has been shown to reduce the average 24-hour urinary cortisol/creatinine ratio, a key indicator of stress hormone secretion. This suggests that L-Tryptophan can help your cat's body manage its response to stress.
The existing evidence strongly suggests its potential to be a valuable tool in supporting feline emotional wellness. It is often used in conjunction with other calming ingredients like alpha-casozepine, which has shown anxiety-reducing effects in cats.
Why we use it
Why we use it
When it comes to your cat's well-being, you want solutions that are both effective and safe. L-Tryptophan offers compelling advantages:
- A Natural Approach: L-Tryptophan is a naturally occurring amino acid, making it a gentler option compared to some pharmaceutical interventions.
- Supports Natural Brain Chemistry: Rather than directly sedating your cat, L-Tryptophan works by supporting their own body's ability to produce calming neurotransmitters like serotonin.
- Suitable for Long-Term Support: As a natural dietary component, L-Tryptophan can be suitable for long-term use to help manage chronic stress and anxiety.
- Fewer Reported Side Effects: Unlike some medications that may have potential side effects, L-Tryptophan, when used appropriately, is generally well-tolerated.
Alpha-casozepine

Benefits and why it matters
Benefits and why it matters
Imagine a calming message gently soothing your cat's nervous system. That's how Alpha-casozepine works! This special peptide, originating from milk, interacts with your cat's brain in a way that promotes relaxation without causing drowsiness or other unwanted side effects.
Think of it like a natural key that fits into calming receptors in the brain, specifically the GABA receptors. By binding to these receptors, Alpha-casozepine helps to quiet the "fight or flight" response, reducing feelings of anxiety and stress. It's a subtle yet effective way to help your cat navigate stressful situations with greater ease and comfort.
What the science shows
What the science shows
Science supports the calming effects of Alpha-casozepine! Studies have shown that this remarkable ingredient can make a real difference in your cat's behavior:
- Significantly lower stress scores: In one study, cats given Alpha-casozepine before a vet visit showed significantly lower stress levels as reported by their owners.
- Improved cooperation: The same study also found that these cats were more compliant during veterinary examinations, making the experience less stressful for everyone.
- Reduced physical signs of stress: Another study observed a significant absence of sweaty paws in cats treated with a higher dose of Alpha-casozepine during stressful situations at the vet clinic. This clearly indicates a reduction in their physical stress response.
- Trusted by behaviourists: Animal behaviour specialists recognise the positive impact of Alpha-casozepine on cats experiencing anxiety.
Why we use it
Why we use it
Alpha-casozepine offers significant advantages over some other solutions for managing feline stress:
- Natural and Safe: As a natural ingredient derived from milk protein, Alpha-casozepine is considered very safe for cats. It's classified as a nutraceutical, similar to a food supplement.
- No Risk of Addiction: Unlike some pharmaceutical options, Alpha-casozepine carries no risk of addiction. You can feel confident giving it to your cat as needed without concerns about dependency.
- No Significant Side Effects: Studies and real-world experience suggest that Alpha-casozepine is generally well-tolerated by cats, with no common or significant side effects reported in the sources. In contrast, some anti-anxiety medications can cause drowsiness or other behavioural changes.
- Gentle Action: Alpha-casozepine works by gently modulating brain activity to promote calm, rather than forcefully sedating your cat. This means your cat can remain their alert and loving self, just more relaxed.

No. Stylla Calmness supports emotional balance without causing sedation. Your cat stays alert and responsive while feeling more at ease in stressful situations like vet visits, travel, or changes in their environment.

How long does it take for the product to start working?
Most cat owners observe a calmer attitude within the first 1 to 2 weeks of daily use, especially during predictable stress triggers like travel or vet visits. However, deeper emotional balance often develops over 3 to 6 months of consistent administration. Long-term use helps maintain emotional stability and prevent stress buildup over time.
