Major cities have already tried using feral cats to deal with rats and mice and the number of places where that has worked is very close to ZERO.And the other problem is that no legitimate SPCA or rescue is going to give you domesticated cats to leave outside 24/7.

No vacancy...doesn't matter if it's a month to month lease, or if the lease is midway into a year commitment.What you want is your unit occupied, What happens in peoples lives is job changes, relationship changes, and housing plays a big part.I managed a large complex, we had roommate situations all the time fall apart for residents, divorce, splits, domestic abuse (any kind relationships not just married couples).
