My cats eat bugs, though I would rather if they wouldn't. My younger cat is a huge glutton, and I would really expect him to be the one who is chasing and eating the bugs, but other than running after them for a short while he's not very interested. My older cat, on the other hand, is the stereotypical ruthless hunter. She chases them very passionately, she puts them in her mouth and then let's them run a little bit more, than catches them again... A few days ago she caught a really big bug, and after she ate him I noticed every one of his legs laying around on the floor. I'm not even sure how she managed to do that. But I really dislike her killing bugs. Whenever I see a bug in my house, I try to catch it and let it go outside. Bugs may not be as cute and fuzzy as cats, but they do no harm, and shouldn't suffer such a cruel death.
