Yes! Rat snap-traps are kept inside a wooden safety box with wire mesh at both ends. These tunnels have a small entrance that allows predators enter but keeps pets out.
For possums, traps are installed on trees that are less accessible for pets (e.g. no low hanging branches) and at a safe height for dogs. We use non-toxic lures that are less likely to attract pets and never use meat or fish bait.
Trap aversion training for pets can also help. This involves bringing a dog or cat near the trap, putting the lure on its nose, and setting off the trap so it gets a fright and associates both the lure and trap with a negative experience.
For people who are still concerned about pet safety, we suggest setting the trap overnight and keeping pets indoors.
