We put most of them up at night

We have a shed now that is their little house at night. ^^
And yeah, we have neighbors like that.
One has even lured them over with poisoned food...
And done other things to them that are unknown, because they simply disappeared.
the other shot one of our cats...he learned quickly though you do not fuck with our cats and grandma >.>
So yeah, there have been problems in the past.
However, at this point any cat deaths should be natural since people know that we are scary cat ladies and you do not mess with us.
