There are a number of online markets and specialty pet stores that buy and sell exotic pets, such as monkeys. Websites such as Primatestore.com are public Internet boards for people who want to buy or sell monkeys. However, it is not legal to own monkeys as pets in all states.
Buying a monkey to have as a pet is not similar to picking up a puppy at the local animal shelter. Monkeys are very intelligent and can be stubborn enough to get themselves into serious trouble. It is also important to keep in mind that monkeys have very long life spans and by taking home that cute baby monkey, a person is making what could end up being a 40-year-long commitment.
Monkeys can be difficult to train, it is nearly impossible to find a capable pet-sitter, and many veterinarian offices won't take monkeys as patients. Also, they are not even legal in all states.
Monkeys can be expensive to purchase, with prices near $8,000, and they cost anywhere upwards of $40,000 over the course of their lifetime. Deciding to get a monkey as a pet is a big decision that should not be taken lightly. These factors should be considered thoroughly before beginning to look for potential monkeys.
