Thanks for checking in nikkubus!
That's kinda what I'm figuring too. When my female did it last year she drank normally, still came out to explore, etc. I would scoop her up once a week to check her to see if she was losing weight or was injured or anything and she was fine all summer. Last year she started eating again at the end of August, but she went off food in early March. Assuming the "schedule" is similar I'm hoping she eats again in Sept. If the male follows the same schedule he sound start eating again in Sept/Oct (he went off food a couple weeks after the female).
The only thing I'm concerned about it how she hasn't grown as much as the male (she used to be WAY bigger than him because she's a couple weeks older, but he caught up when she went off food). I'm attributing it to him having eaten non-stop for his first 2.5 years and she stopped eating at 1.5 years and now again at 2.5, so she's missed several meals. I'm expecting him to plateau now and for her to slowly catch up over the next couple years in between her hunger strikes.
