My male normal (~1000g) has been off food for about 2 months now. My pewter female stopped for about a month and then resumed 2 weeks ago. My younger male (~700g) never went off food, but I did notice his drive to eat seemed a little lower than usual for a bit (had to entice and zombie walk), but it's improved now. I hope my normal starts eating again soon, but he hasn't lost much weight.
