small dry poops no appitite

[ynnub]

so nub doesnt seem to enjoy his hay and kibbles per usual. i havet changed anything but he just doesnt eat nearly what he normally does. also his poops are quite small and hard, and very infrequent.
i was told he needs more fibre, so i have several types of hay for him but he seems disinterested.
he is his normal curious playful self.

is there anything i am missing?

How old is Nub?
What is he eating right now?
How long as the appetite been decreasing?
Is he drinking? If so, how much approx.?

He is 41/2. Hes drinking a little less the usual. Hes eating oat grass and timothy hay and 1 cup twice a day of collard greens carrot tops a bit of kale parsly and coriander. Just a few pellits and a baby carrot. Ive noticed this over the past 3 or 4 days. Hes eating a bit more now that ive changed his diet to what i posted above. I was worried about gi stasis but his poops are not runny hes gained no weight and is his playful binky self not lethargic. Its just out of characted for him.
