Groundbreaking CT Scan Delivers Vital Answers

In November 2025, three of The Big Cat Sanctuary’s most iconic residents underwent an advanced diagnostic procedure never before carried out in the Sanctuary’s history.

A mobile CT scanner was brought on site to investigate ongoing and unexplained medical concerns affecting Luca the Amur tiger, Django the mainland clouded leopard, and Mo the cheetah.

Now, following detailed analysis of the scans, the Sanctuary can share how this landmark moment is already transforming care for these remarkable cats.

While not every finding was straightforward, the CT imaging has provided something invaluable: clarity. With clearer insight, the veterinary and keeper teams have been able to refine treatment plans, make informed decisions, and safeguard each cat’s long-term welfare.

Django’s scan was carried out to investigate apparent bilateral hindlimb lameness. Encouragingly, no significant skeletal abnormalities were detected.

Separately, further diagnostic investigations identified an abdominal mass. A follow-up ultrasound confirmed that while this mass had stabilised, an additional mass was identified on his right testicle. Early indications suggest this could be a tumour.

Crucially, advanced imaging has enabled early detection.

Further analysis will now determine the best course of treatment, giving Django the strongest possible outlook. At this stage, it is anticipated he will still be able to participate in the European Breeding Programme for mainland clouded leopards, ensuring his valuable genetics continue contributing to the species’ future.

Mo was scanned to assess chronic intermittent lameness in his left forelimb.

The imaging confirmed:

• Significant osteoarthritis in his right shoulder

• Tendon inflammation in his left shoulder

While surgery is not required, the scan has allowed the team to implement a structured long-term analgesia plan to manage discomfort and maintain mobility — ensuring Mo can continue to live comfortably and confidently.
