My cats just torture the roaches, but don’t eat them.
I routinely find roaches stuck on their back playing dead.
Our recently departed Attack Cat (TJ) had at least 2 copperheads to his credit. He didn’t eat them, either. Just deposited their mangled corpses at our back door step.
TJ is now in that great litter box in the sky....waiting to catch the obama’s playing in a sandbox..... ;)
