Yeah if he is 2200 grams or around there, 2 adult mice every 2 weeks is underfeeding. That's ok though, just up it slowly till you find the happy size. Easier to correct underfeeding than overfeeding. My red tail boa lived luxury and was feed every week on medium rats. She is now pretty fat and now I gotta do tough love and like I said, cut her down to 1 medium rat every 2 weeks or when she takes a poop and is empty for a few days so I can slowly get her to lose weight. Its harder as with no food, any animals body goes into conservation mode and starts to hoard every calorie since it thinks its starving and thus losing weight is even harder. And its even harder as she is a lap snake who loves to have her head and body rubbed and come out and sit on me while I do stuff around the house or go outside so I feel bad cutting down her food![]()
