my guy hit 1200 and slowed down quite a bit. He gets 1 small rat every 2 weeks. It's what works for him.
TBH, I think there's times during the year when he could definitely take a small rat 1x per week, but there's also times during the year when he could take 1 rat per month. Not sure why that is or what dictates it, but he was voracious in September. October, not so much.
