Did you notice behavioral changes or any change in defecation or increased activity after switching? Did they fast longer or shorter after switching or was it not at all? Or have you done this all along? I really want to know if anyone switched to a bimonthly diet in a 5+ year old and if there were any noticeable changes in behavior or digestion. I would adore every 2 weeks as it would stretch the rat supply twice as long which would me half as much annually.
I see JodanOrNoDan has done it and really have been temped to try it out and see how his weight and behavior changes if any. Cost of feed is secondary to health and if spreading out feeding in mature snakes improves health, I am all about that.
Fatty liver is a problem in just about any animal overfed and one of the main reasons I keep/kept every animal I own/owned trim. Never had an animal die early.
