What's more, monkeys used for tourism receive little or no veterinary care, according to WFFT. "They are malnourished and imprisoned as slaves for their short span of useful life, then killed or abandoned to make way for the next money making animal," the organization writes.
The Monkey Centre did not reply to The Dodo's request for comment.
If you'd like to donate to the WFFT, which helps to rescue animals from the tourism trade, go here. If you'd like to volunteer to care for rescued monkeys in Thailand, go here. If you're in Chiang Mai and want to visit wild animals, consider Elephant Nature Park.
