They have ads like that on CL often. High price animals (typically morphs or dog breeds) that need to be re-homed. Even though they are listed in a local city when you contact the person they are out of state/country and want money for shipping the animal to you. I responded to one for dog once even though it was listed as being in my city the seller said they were out of state. A state I was actually flying to the next week for work, so I offered to personally pick it up and ship it on my own dime. Of course at that point she terminated all contact.

At best this is probably a scam- at worst they may be stolen. I'd steer clear.
