You know what? This is below us.
She has some opinions that are troublesome. But she's still a person, a human being. And if you were here, you'd get repremanded for that comment. Her not being here doesn't make it okay to be that insulting of a person you've never met.
If we, collectively are gong to treat her like that, then we don't deserve to have the problem solved, because we are small people with fragile egos who have to bring other people down so we can feel big and powerful and proper.
She's a human being, and it is quite possible she loves that cat as much as any of us love our pets. Her ignorance and unwillingness to take personal responsibility doesn't eliminate that.
Think about that for a sec - we're talking about taking away a beloved pet because it is inconvenient, and the owner seems difficult to deal with. I dunno about you, but I've had pets stolen before, and it isnt' fun. Think about that as you consider your course of action. What woudl happen if someone made sure your dog or cat went away and never returned.
