Break into my home, their likely to get hurt. On the property line is
"Watch Dog on Duty". Lucky bites first then barks, but that is how he was trained. At night (or were not home) he is inside the house, and has free reign any time he is inside.
The burglar makes it past Lucky, they have to deal with my attack cat. Hoppitty sits on top of the door, and has been known to jump on strangers, unless she is told it's okay.
