13-foot alligator gets CT scan

This poor alligator has been in agony with a loss in appetite and weight.

So doctors decided to give the 13-foot reptile named Casper a CT scan to find out what's troubling him.

One of the keepers at Jungle Island in Miami said: "We really wanted to find out what's going on and this was the least dangerous, least invasive way to do it."

Casper also suffers from melanoma, which means also has a lighter than normal skin tone.

The results of the CT will be sent to vets at the University of Florida who will hopefully learn more on how to help him.
