My neighbor has a cat which she lets freely roam the neighborhood. The cat has taken a liking to hanging out in the bed of our truck and is setting off our camera all hours of the day and night. It's especially irritating during the overnight hours. The cat is becoming defensive of our yard as well, and woke up my entire house at 3AM night before last with a loud cat fight right in our driveway.

I feel bad for the cat too. Where we live, the temperatures are starting to drop into the low 40s and high 30s overnight. We cannot take her in, as we have two indoor only cats already.

The cat is also defecating in our yard, and my pom puppy has found and attempted to consume the turds on more than one occasion.

What options do we have to deter this cat from using our vehicle and yard as its personal hangout and bathroom? The neighbor won't keep the cat inside.
