$2,985.75 for 6 mutt dogs?

We listed 6 mixed breed Rottweiler and Husky pups for free. My wife took a call from a guy who said he wanted all 6 and immediately I got suspicious. A guy I knew listed 5-6 kittens and one guy said he would take them all. When his wife asked why he wanted all of them, he didn't even blink, he looked at her and said, "I'm going to feed them to my snake." She cussed him out and told him to leave. This guy told my wife he wanted them to guard his business and he would pay for the shipping. I still didn't believe ut. When i got home a Fedex letter was hanging from the gate with a cashiers check for #2,985.75 The return address is "Keller Labs Inc. Exposition Blvd in Sacramento California. I've been Googling it under the California Yellow pages to no avail. If it exists, it is an animal testing lab that will use these puppies for medical studies or worse. Can anyone provide me a link to this supposed address?

I got the answer, it's a bogus cashier's check. A common scam, it'll clear fine at first, then the "buyer" will ask for half back as he can no longer use the dogs. By the time the smoke clears, you are out of money if you bite. This is the second one my wife has gotten.
