Pet population systematic review
This was the first systematic review published by the CEVM. The aim was to evaluate the methods that have been used for estimating the size of owned cat and dog populations, and assess the biases associated with those methods.
A comprehensive, systematic review was conducted using a range of different search terms for cats, dogs and population. Methods for estimating pet populations were identified and assessed for bias.
• The main biases of the studies included selection bias, non-response bias, measurement bias and biases associated with duration of sampling.
• Careful design and planning of studies is a necessity before executing a study to estimate pet populations.
We would like to acknowledge the pet population steering group for their involvement in this study, notably Dr Vicki Adams.
