Well, 10pm feeding went pretty well, he was back to 408g (seems he's peeing or something, he went down 5g in the last 3 hours), but he took about 4-4.5mL of pedialyte, and then another 2.5mL of pedialyte with a tiny bit of the mush mixed in, he was 419.6 when I put him back in his cage. He was shaking again when I took him out, so I think I'm going to give him more every 2 hours. Does anyone know how much fluid I can give him without hurting him, should I just give him as much as he will take?
I don't know if he's constipated so much as he just doesn't have anything in him to form poos. I was feeling his stomache and it feels full(kind of odd on his poor skinny little body), but not hard or tight or hot, any of those would be an indication of constipation wouldn't it?
I've never needed any other vet, so I have no Idea where there might be one I would trust, but I'll go look around online right now. I will not take him to an afterhours emergency vet unless they specifically treat chinchillas, I think he feels safer here, and I'm pretty sure getting just as good if not better care(sad but true).
Thank you so much for your help and concern CT! Everyone keep your fingers crossed for the little guy, I'll keep you updated.
