Yuji, a six-week-old patas monkey at the Guadalajara Zoo in Mexico, is gaining popularity online after videos of him clinging to a stuffed toy for comfort went viral. He was separated from his mother just hours after birth when she showed signs of being unable to care for him. Weighing less than half a kilogram at birth, Yuji required immediate care and was placed in an incubator to stabilize his condition. Since then, he has been under the constant supervision of a team of veterinarians and biologists. The stuffed toy has become an essential part of his daily routine, acting as a substitute for his mother and providing him with a sense of security. Zoo staff rotate different toys to ensure cleanliness while Yuji remains on a milk-based diet and is still being bottle-fed. Experts indicate that he will not be introduced to other monkeys until he is older and stronger, which could take several months. His story has sparked discussions about the ethics of raising animals in captivity, with some activists criticizing the practice. However, zoo officials maintain that intervention was necessary for Yuji's survival. As videos of him continue to circulate, Yuji's story is becoming one of the most talked-about animal moments on the internet.
