PICO question

In domestic cats in a shelter setting, does clicker training decrease proxy measures of a stressed emotional state (behavioural or physiological) compared to no clicker training?


Clinical bottom line

Category of research question


The number and type of study designs reviewed

Two papers were critically reviewed. One was a prospective quasi-randomised clinical trial, the other was a quasi-experimental before-and-after study with each cat being its own control

Strength of evidence


Outcomes reported

Both papers reported a decrease in behavioural stress indicators in shelter cats following a clicker training programme. Not all of these decreases were statistically significant and there are large issues with confounding factors in both papers


Preliminary evidence suggests that clicker training can be implemented as one form of enrichment to reduce stress in shelter cats alongside other means. Further evidence is required to demonstrate superiority to other forms of enrichment to reduce stress in shelter cats, especially given the practical limitations of implementing such a programme in most shelters


How to apply this evidence in practice

The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.
