The reason catch and release is illegal judy fyi is because the animals relocated are being put in a new environment with predators and diseases it may not be capable of handling. 9 times out of 10 the relocated animal is killed by another animal or starves to death
I harvest the skulls and different bones from animals to sell so I gas raccoons and opossums. I wrap the cage in plastic than use the exhaust from my car.
It's illegal to catch and release in most areas including mine so most people on here will just dispatch the predator. I think it's more likely they see the trap as a threat and will just avoid the trap but keep coming around.
