Preliminary results from a University of South Australia project has revealed domestic cats travel a lot further than expected during night walks.

Of the 16 cats analysed so far, results from the sample week vary from localised exploration of under half of a hectare to travels covering more than 29 hectares. "We've looked at cats in urban areas around Adelaide so far," Dr Philip Roetman from UniSA's Citizen Science initiative said.

Researchers have been quite surprised by the variation in travels revealed as GPS tracking data is processed. "Some of the cats are basically just going over the fence and having a look, whereas other cats are trekking into local fields and going quite a long way," Dr Roetman said.

How cats are being tracked

The cat tracker project is a partnership research program being conducted by the University of South Australia, Your Wildlife in North Carolina and Victoria University in Wellington.

Each organisation plans to monitor the travels of a minimum of 500 cats to provide a sample size of more than 1,500 to analyse habits of particular breeds of domestic cats.

Cat owners nominate their animal for tracking locally via the Cat Tracker website and fill out a small questionnaire to provide details on the area they live in, breed and characteristics of their cat.

Once selected, owners are sent a small GPS unit and harness that is placed on the cat.
The GPS does not activate until 48 hours after being fitted and then captures the cat's movements for the next seven days before the unit is returned for processing.

Discrepancies are automatically removed from data, with unusual movements, such as trips to the vet, also recognised and discarded. "One owner had no idea that their cat was going out of their back garden, and another was really surprised to see just how far their cat was going," Dr Roetman said.

Results so far showing most cats home-based

Dr Roetman said it was still too early to predict any patterns with movements of the animals monitored locally. "The results from the US, where we are collaborating, that have tracked about 100 cats so far are finding that most of the cats aren't travelling very far," he said.

Similar results were beginning to be seen in the samples taken near Adelaide. "We need a lot more data before we can say confidently that we have found some trends in cat behaviour," Dr Roetman said.

By tracking more than 500 cats in total for the project, Dr Roetman hopes to smooth out anomalies such as cooler and hotter weather restricting travels and begin to understand animal ranging patterns better. "Once we have a lot of cats, we will be able to look at those trends and talk to the community about what are those factors that lead to cats travelling further," he said.

Dr Roetman said one goal for the project was to provide potential owners with detailed information about the differing needs and ranges of different cat breeds, to help match cat and owner personalities.

"People may decide to choose a certain breed because we found that they don't go so far, so they are less likely to get into territorial fights with other cats, they are less likely to encounter dogs, they are less likely to annoy neighbours," he said. "I think people are very interested in that sort of information so they can make their own decisions about what sort of cat to get."

Dr Roetman also plans to introduce projects covering "community-owned" cats and tracking cats' behaviour after owners have relocated to further understand the movements and habits of the animals.
