I give my glider the sgs diet as it's the easiest for me as I'm in the UK. Recently he has stopped eating as much as he use to. He's still very active and does eat treats and some of the food.I was thinking this could either be because 1) he doesn't like the mix of food i used this time or 2)I recently moved his cage so he can tell if it's day or night (maybe this stressed him out)?
I really hope it's one of these 2 and not health related :(. He ate a lot yesterday but a lot less today and he wasn't eating much the days before.
Some nights mine don't eat much. I think it could be weather related, moon phases or females in heat. I wouldn't worry unless it lasts more than a couple of days.
