The gaol (jail) at Wellington in NSW had to be evacuated because of the mice plague. They got into everywhere and caused a major stink and health issue and the whole prison was emptied until it's fixed. Major job to get dead mice out of walls and floors.
As for more cats. No way! Australia is over run with feral cats and foxes. We have the worst species extinction rate in the world with small marsupials and numerous other species close to being wiped out. Cats and foxes (as well as land clearing and bad management) are slowly wiping out our native species.
Cats are Number One on our hit list when out bush.
