Earlier this month, Oakland Zoo in California assisted in rescuing an 8-month-old female tiger with severe bone fractures due to calcium deficiency. They found 10 pathological fractures in a CT scan, and also noted 50 percent muscle atrophy.

The fractures appeared to be at various stages of improper healing, resulting in abnormal angles in her limbs. Said abnormal angles means the animal was unable to move properly, creating muscle atrophy associated to those limbs.

The tiger's recovery will involve building calcium, physical therapy, and after months of recovery of the limbs, possibly surgery. The zoo is cautiously optimistic for a full recovery though, but arthritis may develop in later years.

The tiger cannot perform natural behaviors due to medical issues and is currently receiving specialized enrichment for mental health and to help build muscle. No history on her case because it is an ongoing legal battle.
