A Brisbane student wants your cat’s poo in order to find out the impact your furry feline is having on local wildlife.

Griffith University Honours student Renee Piccolo has put out the call to Brisbane and Gold Coast residents to take part in an online survey to help reveal where domestic cats roam and what they hunt.

Domestic cats have a natural instinct to hunt and a Griffith University student wants to know what they are eating.

Domestic cats are by nature instinctive hunters and are more likely to kill birds and lizards, according to a Department of Environment and Heritage resource on responsible pet ownership.

This behaviour is exemplified in feral cats, which "spread disease and threaten native wildlife", a Brisbane City Council spokesman said last year.
