As a pet seller, I've noticed that Craigslist often bans my ads selling pets. After researching, I found that this is because Craigslist prohibits the sale of pets to prevent animal cruelty, scams, and illegal activities. They do, however, allow rehoming ads with a small adoption fee. To avoid getting banned, I can try posting my ads in the "community" section under "pets" and ensure I follow their guidelines. Sharing detailed information about the pet's history, health, and required care can also help me find a responsible and loving home for my pets.
