OTT? No... I really don't think so...

No more than taking a kid who likes to pull the wings off butterflies to therapy is over the top...

Why is it only after the fact that people become really concerned about possible 'warning signs'???

It reminds me of the 4 P's of spouse abuse... 2 of them are Pets and Possessions... If someone will break yer stuff, or harm yer pet, it's not that much of a leap for you to believe that they might harm you...

I'd involve the police if someone booby-trapped my kitty door... abso-frigg'n-lootly...

Especially if it's someone who's willing to cause harm to a living creature over something like a little cat turd...
