My male uro is 25 years old. He suddenly has gone on a hunger strike and looks awful. Nothing about his enclosure has changed. His UVB bulb is maybe 6 months old. I will change it out as soon as the new one arrives. Does anyone have suggestions on how best to encourage him to eat or to help him feel better? I know 25 is old. I’m not sure if we are just nearing his time or if I can help him in some way. Thank you
