See, I do know of pets that have been lost due to weather and predators in Australia. Pigs dying of heat stroke every summer (ACS Brisbane probably gets a dozen calls a week during the hot summer months about dead of dying pigs in outdoor cages). Pigs being eaten by snakes (one particularly traumatic one where the snake got in, ate one pig, killed another and was unable to get out again so the third pig was left permanently traumatised because of that), Pigs being eaten by dogs (even the family dog breaking into 'dog proof' cages and killing them), taken by 'human predators'. For me, there are just too many unknown variables with keeping pigs outdoors.
Same with rabbits, we have both the Calici and Myxo in the wild rabbit populations and whilst there is a vaccine for Calici...there is none in Australia for Myxo. I (not being a rabbit owner, or part of a rabbit group, apart from a couple fb rescue groups) still hear about a dozen rabbits dying of Myxo a year (outdoor bunnies, you do get some indoor bunnies getting it but with the right precautions it's a lot harder).
