Purchase from a certified breeder
It’s recommended to buy a marmoset monkey for sale from a breeder certified by the U.S. Department of Agriculture (USDA) like Poggi’s Animal House. Doing so not only guarantees that buyers have the necessary papers for owning a pocket monkey, but it also assures that the little one is well taken care of when it’s separated from its mother. Baby pygmy marmosets can get depressed and sick when they are taken away from their mothers, so it’s important they are weaned properly to ensure their health.
Check with local authorities about pocket monkey ownership
Some states require special permits and licenses before people can keep pygmy marmosets for sale, while others don’t. Aspiring owners should first check state policies before making any purchase.
