The Big Flea Project

The Big Flea Project1, our sister project to The Big Tick Project was conducted in 2018 and results are now live.

1,475 animals were examined (812 cats, 662 dogs, 1 unidentified), from 326 vet practices throughout the UK: 5 random pets a week per practice. Fleas were collected from March to June 2018, sent to the University of Bristol, identified and their DNA extracted.
