My adult male has been off food since the beginning of October and he weighed in at 1498 grams. He took one small f/t rat in January but that is the last time he's eaten. Today he weighed in at 1276 grams. He seems healthy and interested in food, but right before I think he'll strike, he appears to lose interest. Any suggestions? He used to be a great feeder. Never missed a meal. His usual prey before the hunger strike were f/t medium rats.
