Progress update: He has eaten literally almost all his pellets, and hay. He has been drinking water, there are lots of poop. None are super small and hard which is good. He is biting wood more, and he sleeps inside his batman cave which he (usually never does) which is odd, he is a little lighter, and just by looking at him looks skinnier, but he is eating and shows definite interest in food, always see him eating and begging for treats. I got critical care yesterday, and tried feeding him, he wouldn't have it, but he did bite the syringe twice so he did get two tastes. I mixed critical care and some herbs and left it in a bowl to see if he would eat it, not sure if he did, but it does look like it was eaten or may be the water shrinks it down after a while, idk. I sprinkled the critical care powder on top of his pellets, and they were gone the next day so I think he ate it. Also I was worried cause the flavor is Apple-Banana. Is this flavor ok for chinchillas? Anyways he seems more pissed lately, but still gentle, biting more food, a little flushed like his ears get pinkish more easily, and a little lighter/skinnier. I obsess over every detail, also his stomach is round and out i think he's just fat cause he's always looked that way but it has gone more in after his bloating went away, he absolutely hates the medicine and i don't think he needs it, i dont want to force feed him when he doesn't need it.
