There is a new call for pet cats to be confined to property boundaries, after a university researcher captured video showing a cat attacking a southern brown bandicoot.

The species that was once a common sight in south-eastern Australia, especially coastal areas, is now nationally endangered and listed as threatened in Victoria.

Deakin University PhD student, Sarah Maclagan, is researching the habitat use of the species and the threats to its survival.

She recorded the footage at a research site near Koo Wee Rup, south-east of Melbourne, and explains it shows a domestic cat carrying a young bandicoot that was later found dead near the camera.

"I found the body later that same day, missing its head and its front legs," she said.

Ms Maclagan says a lot of councils have ruled that residents need to keep their pets confined to property boundaries, but a lot of people do not take the necessary steps to ensure their cats do not jump fences.

"It's not just feral cats and stray cats that are the problem, it's also domestic cats. Even though they might be well-fed, they still like to hunt," she said.

"The key thing that's come up for me is that cats really do need to be restricted to people's properties."

The response Ms Maclagan has received from cat owners has been mixed.

She has heard a lot of stories of cats sharing their food with bandicoots on the back porch.

But she says adult bandicoots have far greater defences than their young, which are easy prey for a cat.

Bandicoots are active during the day, so confining cats just at night only is not the answer.

"We're not trying to demonise cats or cat owners. It's just about managing them responsibly so that wildlife aren't impacted," she said.

In Victoria's south-west, Marion Manifold is leading the Port Campbell Community Group's push to save the southern brown bandicoot.

She personally supports moves to prevent pet cats roaming and says the group's fauna cameras regularly capture pictures of cats hunting native animals.

But the group is focused on the control of feral animals, especially foxes, and recently received a $25,000 grant from Coastcare for an education program.

Ms Manifold says encouraging landholders to control foxes, feral cats and wild dogs is the main goal.

"I think anyone who works with these sort of animals, monitoring them, can see the impact that the ferals are having," Ms Manifold said.

"It's number one to get local Landcare networks, to get the landowners on board and then all we need to do is get some funding so that we can keep it on a level keel."
