For the first time since coming out of hibernation in early March, earlier this week both hognose snakes ate the food they were offered. The male had eaten once before; the female hadn’t. Neither was looking particularly gaunt or had anything else visibly wrong with them; I can only surmise that they simply weren’t ready to come out of hibernation yet. Both, however, had shed shortly either the night before or the day before they were offered food this time, so maybe they need a post-hibernation shed before they start eating. (Note for future reference.)
Now let’s see if they’ll breed!
