Call up your agricultural department.......they will be able to identify your critter. If your department is anything like ours (ours is the top!) they will also put you in contact with the state trapper division, and they can help you get the beastie trapped. Ag department is at no expense (in CA, anyway) trapper can vary. We had the trapper out for dogs in our sheep, and that was no cost. Or, the ag department might loan you a trap.
