Place your cats litter box out side. Place an ad in your local newspaper, and contact the local radio stations. Offer a reward if you can. Others Call the local veterinary clinics, especially those that offer boarding. Even if there have been suspected cases of pet theft in your area, don't assume that your pet is the latest victim.
Pets are far more likely to stray from home and get lost than be stolen.
However, if you believe your pet has been stolen, notify the local police and animal control departments immediately. Keep searching even when you have little hope left. Animals who have been lost for months have been reunited with their owners. Protect your pet from getting lost again. Always keep a collar and identification tag on your pet.
