After a few bad experiences, our cats are not allowed outdoors (with the exception of their cat run). We had one cat someone shot with a pellet gun. Lucky for us, and her, she lived. The pellet went through her ear and lodged between the skull and skin on top of her head. Then we lost one for about 2 weeks. He went in one of the storm drains, hurt his hip, and couldn't get out. We fortunately heard him meowing one evening as we were posting lost pet posters. My husband unscrewed the storm drain, I held on to his legs as he lowered inside and pulled him out (would've been a good chance to get rid of him) hahahaha...JUST KIDDING. Anyway, we never let them out to roam.
