Writer and illustrator Kaye Kessing has appeared on a national news program, speaking of her desire to see feral cats on the national menu.

Appearing in a story on SBS news program The Feed, Ms Kessing spoke of how a dish she created using feral cat launched her into the international spotlight.

"To make a point about the problem that feral cats are causing right across Australia I cooked a 'catterole' in [a] bush foods competition," she said.

"Aboriginal mob out bush have eaten cat for a long time, if it's good enough for them it's good enough for me."

Ms Kessing went on to describe the backlash she received, including death threats, when the story gained international media attention.

"I had a large amount of hate mail from all around the world, it went viral," she said.

"But I must say I added up all the comments that came in via the news articles but the majority of feedback was positive."

Feral cats present a serious threat to biodiversity in Australia.

As predators for a large range of native wildlife, it is estimated they consume an average of five small vertebrates a day, including reptiles, mammals and birds.

Ms Kessing said putting feral cat on the national menu would be one way of helping preserve Australia's vulnerable native animals.

"People just have to get over their emotion," she said.

"They have to realise the critical danger that these animals are causing."

Describing the taste of feral cat as a bit like rabbit, the writer and illustrator said one thing that may sway public opinion about eating feral animals was taste.

"Any wild caught food, it's got a completely different taste, these animals are roaming free and they're eating a wide range of plants and food," she said.

"It tastes a hell of a lot better ... it's much richer."

Alice Springs environmental writer Kaye Kessing says feral cats could be used for human consumption.

Ms Kessing said any feral animal should be considered as a possible food source, including cane toads.

"I don't think there's a line to be drawn," she said.

"I said on The Feed that cane toads would have pulled me up a bit and I guess it's that association with its poison.

"[But] any meat is good food. The thing with eating carnivores is that you must be careful with preparing them ... they can carry diseases.

"The other big point is that any animal that you kill is killed humanely."

Ms Kessing has recently released a children's book trilogy The Bilby's Ring, which explores the threat from introduced predators.
