Looks like a little Kiwi company has produced an awesome product. My cat's a good ratter, but I really want one of things too. We live adjacent to a reserve and small creek, and my cat brings me several rats every month.
It's a small thing but these traps could really make a difference for endangered bird species.
They look pretty fucking awesome. ...for, you know, an automated killing machine. One wonders if the rats ever figure out to beware the pile of corpses. Looks like Possums don't. BTW, it saddens me to watch your possums die. Because they're so much cuter than ours:
They are a little cuter, but we all still hates them nearly as much. They have a nice soft fur, though. They make fake kiwis out of possum fur, to sell to tourists. There was once a bounty on possums, but that just led to people raising the damn things on purpose. Sigh.
