you can't sell live animals on eBay "eBay generally does not allow the listing of live animals or pets on eBay. In restricted cases, some stuffed birds and the pelts and skins of some animals are permitted. Sellers who wish to list these items should review the specific rules in the “Some Examples” section below to ensure their listings comply with eBay policy. We also encourage members to educate themselves on the laws governing the regulation of the sale of animals found in the additional information section." from
