Guadalajara, Jalisco, Mexico – A young patas monkey named Yuji is finding comfort and strength at the Guadalajara Zoo through a unique bond with a plush companion. Born on March 3, the infant primate began his journey under the specialized care of the zoo’s medical team after his mother, Kamaria, struggled to form a maternal bond.
To provide the tiny monkey with the security he needs to thrive, caretakers introduced a stuffed dog that serves as a surrogate mother, offering him a constant source of physical reassurance. This tried-and-true method of assisted rearing is a vital tool used by zoological professionals to protect at-risk offspring.
In Yuji’s case, the process began almost immediately after birth when keepers noticed he was unable to maintain a secure grip on his mother. At the time, he weighed only 443 grams and required an incubator at the Comprehensive Center for Animal Medicine and Welfare (CIMBA) to stabilize his health. Under the watchful eyes of 12 veterinarians and biologists, Yuji has since grown to a healthier 673 grams.
To ensure his environment remains both stimulating and hygienic, the staff maintains a rotating cast of stuffed animals, including a bear and a monkey, so Yuji is never without a clean “parent” to cling to. His enclosure is also equipped with ropes and a small hammock, encouraging the development of the natural motor skills he will eventually need when he joins the rest of the primate troop.
Currently, Yuji’s days are structured around a carefully managed feeding schedule. He receives four daily bottles of fortified milk, with the first feeding starting at 7:00 am as he becomes more independent and sleeps for longer periods. While his story has drawn comparisons to other famous primates who found comfort in toys, Yuji’s path is focused entirely on his eventual integration into the zoo’s larger community.
The transition to a shared habitat with 12 adult patas monkeys and three other infants will begin once Yuji is fully weaned. According to Iván Reynoso Ruiz, the head of the primate section, this milestone usually occurs around six months of age when the diet shifts from milk to a variety of fruits and vegetables.
Until then, Yuji continues to meet every developmental milestone with his plush companions by his side, representing a success story for wildlife conservation and animal welfare in Mexico.
