I've read that sulcata tortoises don't hibernate but I'm just trying to make sure, Tofu is a sulcata tortoise and it seems to be slowing down it walks less usually walks 5 or 6 steps and then stops and lays down I've placed it on grass for it to graze but seems to take only 5-6 bites and then sleeps but when I gave it some cucumber it immediately springs into action and starts slurping the middle part of the cucumber since the outer side is a too hard for it to bite through. It has no problem with opening its eyes just.. not that wide It doesn't have a runny nose its poo looks good (firm moist and has got a bit of green in it but its probably because of the mustard greens I gave it last time). overall it's not as active as it used to be. Should I be worried is it just sleepy or is it trying to hibernate?
And here's a photo of it
