I have fasted my hermann for 3 weeks now with daily soaks, where he also drinks, he started to poop a couple days ago but never managed to get it all out. I was waiting for him to pass it ready to put him in the fridge today but he still hasn’t had this poop come out. Do I wait another week and hope he poops or will 4 weeks be too long of a fasting period? Not sure what to do! He’s 13 years old and always hibernated successfully before.
