Body-building for maggies could be the answer to feral cats . Nowhere to run nowhere to hide. A cassowary on cat food would love cats.

"..be endangered by predictor animals"

A psychic pussy?

Paul the Octopus would know.

However, there is always a critic,

"Mahmoud Ahmadinejad attacks Octopus Paul
Mahmoud Ahmadinejad, the Iranian leader, says Paul the Octopus, the sea creature that correctly predicted the outcome of World Cup games, is a symbol of all that is wrong with the western world"

Mondays need trivia.

The infinite monkey theorem states that a monkey hitting keys at random on a typewriter keyboard for an infinite amount of time will almost surely type a given text, such as the complete works of William Shakespeare or On line opinion. This can be proved. Parrots naturally want to fit in with their flock, so when their companion is a human, they mimic speech to be like their owner. If you’re lucky enough to own an African grey parrot, then you’re likely eager to teach it to speak and edit monkey text to ape political animals.

Hasbeen,

You've brought those that don't know Magpies out to demonstrate their ignorance and as dry cat food is usually grain based with a smatter of meat then it's good food for Magpies.

Is Mise
You're thinking of the Australorp Magpie chook at 4kg , deadly in a surprise neck-swoop.

Magpies have a strong bill with a sharp cutting edge, which can be used for cutting flesh, digging up invertebrates, or picking fruit. Their main diet in summer is grassland invertebrates, such as beetles, flies, caterpillars, spiders, worms and leatherjackets.

In winter, they eat more plant material, such as wild fruits, berries and grains, with household scraps and food scavenged from bird tables or chicken runs, petfoods etc. They will eat carrion at all times and catch small mammals and birds. Occasionally, magpies prey on larger animals such as young rabbits. During the breeding season they will take eggs and young of other birds.

grains : food no. 9 with Whiskas. It ferments and makes them sing a lot.

You don't need dry cat food to feed magpies. All you need is a compost heap. Put your food scraps on it and not only will the magpies become friendly, but you'll also attract lizards!
