It's about participation in a group conversation, and one where we recognize that it's not generally okay to continue to shout at each other when there's other folks trying to have a nice time. I'm willing to presume that you keep your cats monitored, and nothing you've said here would suggest that's not the case. You could, given the circumstances, suggest people take an active role in monitoring a species many of us love that is also notably dangerous for other animals.
