Surgery was performed on the newly arrived leopard at the city zoo on Thursday for the infection on its tail switch.

The animal had reached the zoo on Monday evening from the Neyyar wildlife sanctuary. It looked dull and sluggish, and flesh was sticking out from the end of its tail.

Zoo veterinarian Jacob Alexander said blood tests of the animal had revealed a high count of white blood cells and a high ESR (erythrocyte sedimentation rate). The globulin level was also high, indicating infection. With the wound on its tail bleeding and the animal in discomfort, it was decided to go ahead with the surgery.

The leopard was also microchipped and administration of vaccination has begun.

The animal is barely touching its food, though it is drinking water. “Hopefully, when the infection and pain subside, it will feel better and start eating,” Dr. Alexander said.
