A sloth cannot tell a vet where it hurts. It can, however, learn to climb onto a scale or stretch into position for an X-ray. For eight rescued two-toed sloths at Central Florida Zoo, those small choices are becoming an important part of recovery.
The animals arrived at the zoo in April 2026 after being intended for the cancelled Sloth World attraction in Orlando. Their story began with dehydration, low body weight and serious uncertainty. Now, keepers are using patient, reward-based training to help the surviving sloths take part in their own health checks without unnecessary restraint or sedation.
From emergency care to cautious progress
The zoo's first official medical update said 13 sloths arrived on 24 April. Many were dehydrated and underweight, although they had begun eating and drinking after their initial examinations. Several needed critical care, and the whole group entered quarantine for close monitoring.
Five of those 13 animals later died. A July report from Central Florida Public Media explained that the eight remaining sloths were making progress, but vets were still cautious. Sloths have slow metabolisms and digestive systems, so illness may not always reveal itself quickly. An animal that appears brighter can still face serious underlying problems.
That makes regular health information especially valuable. Weight, body condition, blood samples and medical images can help a veterinary team notice changes. The challenge is collecting those details without creating more stress for an animal already recovering from a difficult experience.
What does cooperative care mean?
Cooperative care teaches an animal to perform a useful behaviour voluntarily. A keeper might ask a sloth to move to a certain branch, present part of its body for inspection or accept a familiar piece of equipment nearby. When the sloth responds, it receives a reward, often a preferred food.
The aim is not to make the animal perform for visitors. It is to give carers a safer, calmer way to complete necessary health checks. The animal can learn what will happen, move at a manageable pace and retain more choice than it would have during forced handling.
Central Florida Zoo calls part of this work human desensitisation. In this context, that means gradually helping the sloths become comfortable with trusted care staff entering their space and carrying out predictable routines. It does not mean encouraging casual contact or turning wild animals into pets.
A scale inside the sloth enclosure
Moving a sloth to a veterinary room simply to record its weight can require catching, carrying and restraint. Instead, the zoo's training team created a scale that can be used inside the enclosure. Keepers can invite a sloth onto it and collect a voluntary weight while the animal remains in familiar surroundings.
That number may look ordinary on a chart, but it can be an important clue. A trend in weight can help a team judge whether nutrition is working, whether recovery is continuing and whether a closer examination is needed. Repeating the process voluntarily also makes it easier to gather useful measurements over time.
Learning to pose for an X-ray
The zoo's sloth care update describes another remarkable behaviour. Chewie and Phantom have been training to hang from their back legs and stretch downwards into an X-ray position.
If that training continues successfully, staff may be able to bring an X-ray plate and portable machine to the enclosure while the sloth holds the required position and eats a reward. Avoiding sedation or physical restraint can reduce risk and stress, while still giving vets the images they need.
It is a clever use of natural sloth anatomy. Hanging is not a circus trick imposed on these animals. It is a normal part of how two-toed sloths move and rest. The training simply shapes a familiar movement into a consistent position for a brief medical procedure.
Choice and control are the point
Associate zoo veterinarian Dr Haley Straub described "choice and control" as a foundation of this approach. Those words matter because wildlife care can easily be confused with entertainment. A sloth taking food from a trained keeper during an examination is very different from a sloth being passed between tourists for photographs.
Cooperative care has a defined welfare purpose. Sessions are managed by specialist staff, behaviours support health care, and the goal is to reduce handling rather than increase public contact. According to the July report, the rescued sloths are not being prepared for photo opportunities. Their future is expected to be in professionally managed, accredited facilities.
Recovery is not a tidy happy ending
Dolce, Pearl, Leeloo, Chewie, Phantom and the other survivors have made encouraging progress, but their story should not be softened into a simple rescue tale. Five members of the group died after reaching the zoo. Staff have been open about the fact that the remaining animals still require close monitoring and that their long-term placements are being worked out.
Responsible rescue work often looks like this: skilled people making careful improvements while refusing to promise more than the evidence allows. A sloth stepping onto a scale or holding still for an X-ray may seem like a tiny milestone. For an animal whose health can change quietly, it can give carers information sooner and with less distress.
The most hopeful part is not that the sloths are becoming comfortable around people. It is that their carers are adapting the medical process around sloth behaviour. Patience, familiar movements and genuine choice are helping these animals receive the care they need without asking them to stop being sloths.
