He had been inside his cage for 12 years and during his time grew a huge mass. Once we decided to adopt him they operated on it. Unfortunately (but not surprisingly) the operation was unsuccessful and he had to be sewn back up with his mass. We were unsure why they chose to do it now at his age of 14. However the important point is that he is recovering and happy. That he is, he acts like a puppy and is very excited.
Lumpy will finish his cause of antibiotics over the next couple of days and we will continue to increase their exercise and integration to the finca pack until hopefully they can be free to enjoy their days with the volunteers and the other oldies Mac and Lio.
