People who don't have collars on their cats and say their dangereous use that as an excuse, and shame on them for not wanting to protect a member of their family by doing something that would identify them. As for indoor cats, I have them and they have a good happy and "long" life. At least when their sick I can get them to a vet before they go off into the woods and die. I hope your Miss Sprinkles is a male seeing as you cannot castrate females!!!! You kids are curious, you going to let them run loose, think about it
