for gods sake, leave the cat alone. Call the owners and ask then to pick up their cat when it is bothering you. Stop making a drama out of this. Cats have been in urban locations far longer than you have and have fared just fine. Great rat deterents.
That's a great idea, why didn't I think of it? Can you give me their name and phone number because I don't know who they are..........thanks!
Chickensoup: thanks for the common sense. In my area, housecats roam the street night and day. Only the most neurotic people need to call the police, the humane society or buy traps. And with a wandering cat (feral or not), you will not see a mouse or rat.
