Interacting with a cat or dog does not reliably reduce acute stress, according to a study published in Frontiers in Psychology by researchers at the Open University of the Netherlands. While pet ownership is linked to general emotional well-being, data from 8,000 real-time records suggests that active contact with pets during high-stress moments may fail to provide relief and, in the case of cats, could potentially intensify negative emotions.
Why doesn’t petting a cat always reduce stress?
The study indicates that while pets provide long-term companionship, they are not immediate physiological “stress-busters.” Researchers collected data over five days by sending participants ten notifications daily, asking them to log their current activities, emotional states, and interactions with pets. The findings revealed that although pet owners reported higher overall well-being, the presence of an animal did not effectively mitigate the impact of specific, high-pressure situations. For cat owners, the study observed that tactile interaction during these moments occasionally heightened the intensity of negative feelings rather than soothing them.
Researchers gathered nearly 8,000 individual data points, allowing for a nuanced look at how human-animal bonds fluctuate throughout a standard work week.
Does pet ownership improve long-term mental health?
Yes, but the benefits appear to be rooted in consistent support rather than reactive relief. According to the Open University team, the primary value of a pet is the sense of connection and the reduction of loneliness over time. Unlike a coping mechanism used only during a crisis, the steady presence of a pet fosters a sense of belonging. This suggests that the “emotional buffer” provided by animals is a cumulative effect of living together, rather than a quick fix for a bad day.
Pro Tip: Managing Expectations
If you find that petting your cat during a stressful meeting or personal crisis makes you feel more agitated, don’t feel guilty. It is a documented response. Instead of forcing interaction, allow the pet to simply exist in the same room to reap the benefits of their companionship without the pressure of physical contact.
How will future research change our view of human-animal bonds?
Future studies are expected to move away from the generalized idea that “pets reduce stress” toward a more specific understanding of how individual personality traits and animal temperaments interact. Previous research often relied on broad surveys, but the methodology used by the Open University—tracking emotions in real-time—sets a new precedent for accuracy. Future inquiries will likely examine whether the “stress-intensifying” effect in cats is linked to the animal’s own sensitivity to their owner’s cortisol levels, as pets often mirror the emotional state of their human companions.
Frequently Asked Questions
Is it bad for my mental health to interact with my pet when I’m stressed?
Not necessarily. The study found that while it didn’t reduce acute stress, it also didn’t cause harm in most cases. The “intensification” of negative emotions is a specific observation during high-stress events, not a universal rule for all pet interactions.

Does this mean dogs are better for stress than cats?
The research notes different outcomes for different animals, but it does not declare one species superior. The key takeaway is that neither species acts as a guaranteed, immediate stress-reduction tool.
How can I better support my emotional well-being with my pet?
Focus on the long-term bond. Engage in shared activities that you both enjoy, such as play or peaceful co-existence, rather than relying on the animal to “fix” a difficult emotional moment.
