One of my previous dachshunds was an insect killer. Actually, he considered anything that wasn't human or another dog as prey, but insects were the most common "kills". When he'd get hold of a cicada, you'd hear it buzzing loudly in his mouth, but after a couple of crunches the buzzing would fall silent.
The male dachshund that I currently have fancies himself as a hunter, but he's really bad at it. He also does not like cats, but whenever he tangles with a cat, it never works out well for him. I wish I wasn't allergic to cats, though.
