For those not on Cubits, here was Janet's reply about what was eating my Monarch cat:
Hi Melanie!
It's a nymph of a stink bug in the family Pentatomidae, a predatory bug. It's a real shame it's feeding on the Monarch cat! I wonder if the cat. had already expired for some reason, it seems a small nymph like that wouldn't be able to kill a cat. of that size off so easily. They use a long feeding tube to stick their prey, then suck out the juices, they possibly inject some sort of liquidising substance first but I'm not sure about that.
It looks like Podisus maculiventris, Spined Soldier Bug which will have it's uses as they will keep other bugs down.
