The story of Bailey the security dog bravely scaring away seagulls from Sydney's Maritime Museum led to great interest across the city.

But in one corner of Redfern, Troop Cat Ed was unfazed

Ginger Ed fearlessly keeps the stables of Sydney's Mounted Police Force free of rats and mice.

"We decided we needed a cat to assist us with our rodent control," Sergeant Kylie Riddell told 702 ABC Sydney's Robbie Buck, as he ventured beyond the iron gates separating Ed and his colleagues from the city.

Ed had recently been adopted by a friend of an officer and was seeking a permanent place to crash.

"We have troop horses here so we thought why not have a troop cat?" Sergeant Riddell said.

"He struts through, past all the constables while they're being given their daily duties.

"After that he patrols the stables while the grooms are mucking out. And usually after that, it's nap time."

Unfortunately for Buck, Ed proved hard to pin down for the elusive interview.

The hunter became the hunted.

"Usually the feed shed is the first place I look for him, he likes to sleep on the straw," Sergeant Riddell said.

"His favourite spot is on the forklift seat."

Eventually, Ed was located by Sergeant Riddell amid the straw and horse feed.

There was a quick meow, before he scurried off, back to his duties — sleep.

"I don't think he liked being woken up from his mid-morning nap," Sergeant Riddel said.
