Baby Monkey Yuji Clings to a Stuffed Dog for Comfort After Separation From Mother

Born weighing just under a pound, a tiny patas monkey named Yuji couldn’t cling to his mother. She couldn’t hold him. Now 6 weeks old and weighing 1.4 pounds, this little fighter at the Guadalajara Zoo in Mexico has captured hearts worldwide for the sweetest reason: he spends his days clutching a stuffed dog, finding comfort in the soft toy that stands in for the maternal bond he never got to form.

When Yuji came into the world on March 3 at the Guadalajara Zoo in Mexico, his mother, Kamaria, was a first-time parent—and things didn’t go smoothly. Shortly after giving birth, Kamaria began acting unusually and struggled to hold her baby properly. Because the infant couldn’t cling to her—a survival instinct critical for young primates—zoo staff made the difficult decision to separate them within hours.

Yuji needed urgent care. He was placed in an incubator to regulate his body temperature and protect his health. This marked the beginning of his assisted rearing, a method zoos use to help vulnerable newborns survive and develop properly. A caregiver later named him Yuji, inspired by a character from Japanese manga, per AP News.

How a team of 12 specialists keeps Yuji thriving at CIMBA

Yuji is being looked after at the zoo’s Integral Centre of Animal Medicine and Wellbeing, known as CIMBA, where a team of 12 veterinarians and biologists monitor his development closely. In his earliest days, the tiny monkey required constant attention, with staff feeding him fortified milk from a bottle around the clock. To provide the warmth and comfort he was missing, caregivers gave him a stuffed toy to act as a substitute for his mother, per Reuters.

To keep things sanitary, staff rotate between three toys—a dog, a bear and a monkey—so he always has a clean one. His crate has been equipped with a small hammock and ropes to encourage physical development. As he’s grown stronger, gained weight and started sleeping longer, his feeding schedule has adjusted to four bottles a day, starting at 7 a.m.

There’s no confirmed date for when Yuji will move to a shared habitat with other patas monkeys. According to veterinarian Iván Reynoso Ruiz, that step will happen once Yuji transitions from a milk-only diet to eating fruits and vegetables—likely around six months old.

How Yuji’s story compares to Punch the monkey

If Yuji’s story tugs at your heartstrings, you may remember a similar tale from not long ago. A young male Japanese macaque named Punch was born in July 2025 at Ichikawa City Zoo in Japan and became internationally known in early 2026 after videos showed him clinging to a stuffed orangutan toy for comfort. Like Yuji, Punch had been abandoned by his mother shortly after birth, and zookeepers hand-raised him with the toy as a substitute for maternal contact.

Because macaques are highly social animals, Punch initially struggled to integrate with the troop and was often pushed away by other monkeys, which made his attachment to the toy especially noticeable. His story went viral, drawing emotional reactions and increased visitors.

However, Yuji’s situation is different—unlike Punch, he hasn’t yet interacted physically with other monkeys at all.

Stories of hand-raised baby animals stir strong emotions, but they also raise real questions about what’s best for the animals themselves. Yuji’s care has sparked thoughtful discussion among animal welfare advocates and zoo professionals alike, with both sides offering perspectives rooted in genuine concern for creatures who can’t speak for themselves.

Animal rights activist Diana Valencia argues that animals should live and develop in their natural environments, saying they have the right to grow and live where they belong. In response, Reynoso Ruiz explained that modern zoos play an important role in protecting species facing global threats. He said intervening was necessary to save Yuji’s life and that without this care, the infant likely wouldn’t have survived in the wild.

For now, Yuji clings to his rotating cast of stuffed companions—one small act of comfort keeping a 1.4-pound monkey alive, one bottle at a time.
