Stop the selling of Animals on Craiglist

People put their family pets on Craiglist that they have had most of their lives ! And some of the reason's i read on as to why they were getting rid of their dog or other animal was pretty pathetic ! And i think it's just cruel because they ask a rehoming fee as well for a older animal that they have had between 5 and 8 years or better ! It's mainly they should just stop Craigslist from selling animals . There are other sights that are strictly for getting rid of their animals ! And what gets me is The Ad is Free and they want to get rid of a animal they have had forever and here they charge a rehoming fee ! In my eyes it just aint right ! They should stop selling animals all together !
