You can be your own pet detective: How to find your lost pet
As the president of a private investigative agency with 5 offices and 22 investigators, we regularly get calls from people that want us to track down and find missing or lost pets. I am very sympathetic, but I will not take your money or your case.
The reality is that you don’t need a private investigator. When it comes to finding a lost pet, you honestly have the ability to do everything a PI can do.
