It doesn’t matter what he was using it for on his own property. Jesus.

If you make the decision to let your vulnerable pet outside, then when that pet dies because of getting hit by a car, or picked up by a neighborhood freak to do god knows what, or eats something toxic to them, then that is on the owner who decided to also willingly expose their pet to hazards like that.

OP killed Milo.

Then how is it the neighbors fault that the cat died? OP being a shitty pet owner is what killed her cat.
