I recently completed my PhD with the Anthrozoology Research Group, within the Animal Welfare Science Centre, studying cognition in dogs.
I am currently researching pet-keeping practices of pet owners in Australia and world-wide. Address: Anthrozoology Research Group School of Psychology and Psychiatry Building 17 Monash University Wellington Road Clayton, VIC 3800 AUSTRALIA

These mechanisms deceive us given the right set of circumstances, correcting visual input where a correction is not necessary. Investigations of non-human animals' susceptibility to geometrical illusions have yielded contradictory results, suggesting that the underlying mechanisms with which animals see the world may differ across species. In this review, we first collate studies showing that different species are susceptible to specific illusions in the same or reverse direction as humans. Based on a careful assessment of these findings, we then propose several ecological and anatomical factors that may affect how a species perceives illusory stimuli. We also consider the usefulness of this information for determining whether sight in different species might be more similar to human sight, being influenced by contextual information, or to how...

A representative sample of rabbit guardians (n = 93, representing 63,000 people) and bird guardians (n = 203, representing 157,000 people) in Victoria, Australia, completed an online survey. Items were related to the environmental, diet/exercise, behavioral, social, and health management practices used by guardians. Guardians sometimes meet their companion animals' welfare needs, but they do not always engage in best practices. Most (79%) bird guardians reported that they interacted with their birds daily, but only 68% of rabbit guardians did the same. Likewise, 32% of rabbit guardians and 55% of bird guardians never had their companion animals vaccinated. These results may be used for educational campaigns for improving companion animal welfare.
