"Pet Adoption Ads"

1)"small adoption fee" does NOT mean "sale price". Pet adoption/rehoming fees must be small, stated in actual $$, and justified by recent vetting expenses (spay/neuter, shots, worming, microchip, etc). You can't charge for market value, the price you paid for the pet, accessories, care/labor, food, or anything except the recent care performed to get the pet ready for adoption. Why?
Because craigslist staff asks you to, here:  https://forums.craigslist.org/?act=sticky&ID=40 

2)You should list your fee in the ad in actual dollars. Saying "rehoming fee applies" isn't enough. You may be flagged on suspicion of being a pet sale in disguise.

3)If you're rehoming a pet for free, make sure you include the word "Free" in both the title and the body of the ad. It's also a good idea to specify all measures you will take to ensure the pet goes to a good home.

4)If you're rehoming a puppy (and kittens soon), it must be at least 8 weeks old to be adopted.. Saying "will be 8 weeks on..." isn't enough. You may be flagged on suspicion of circumventing California, and other state's laws.http://www.animallaw.info/statutes/stuscacalpencode597z.htm

5)Pet adoption ads belong in the "community" section, under "pets". Advertising a pet adoption anywhere else is miscategorized.

6)Pet services ( pet sitter, groomers, etc.) ads belong in the "services" section under "pets". Advertising pet services anywhere else maybe miscategorized.

7)All pet animal parts, blood, or fluids - including but not limited to stud/breeding services are prohibited on craigslist.http://www.craigslist.org/about/prohibited.items

8)Household pets of any kind including but not limited to dogs, cats, primates, cage birds, rodents, reptiles, amphibians, fish, are prohibited to be sold on craigslist.http://www.craigslist.org/about/prohibited.items

9) Rescues and shelters must follow the same rules as everyone. Overposting may become an issue with rescues and shelters that do not play fair.
