I've got a 1991 Toyota 4Runner that I have to park outside. A few weeks ago it didn't start. I looked under the hood and found the spark plug wires, vacuum hoses and other wiring had all been chewed through

. I repaired the damage--but I didn't do anything to keep this from happening again--sure enough, yesterday the car didn't start--the wires and vacuum hoses are destroyed

. It's likely a rabbit--they are everywhere! I'm in northern Colorado.
Do you guys have any ideas on how to keep this from happening again?
