I can't tell anything about branches in the thorax. No idea. Anybody else seeing anything that shouldn't be there? if it's fluids or mucus, what does it mean for him? (I know if someone overdoses lactated ringers, the complication could be fluids in lungs, do you think it could be the case?)
Regarding critical care. I will explain. The main thing that I was observing that he was eating in the past were vegetables. the second - pellets. He was eating no hay, drinking no water. maybe some grass in the yard.
Now he ignores vegetables mostly (eats very little), I am not serving any pellets since he kept flipping it over indoors. He gets fluids via sub-q injections. It APPEARS to me that he eats absolutely nothing or next to nothing, which leads to stasis, right? I see him sitting IN boxes with hay in position like he is struggles to poop (they are huge boxes like litter boxes and I put some stuff under them to prevent leakage if he pees). {The reason why I use huge cardboard boxes with no top filled with hay is because they started ignoring regular plastic litter with wooden shavings some time ago. I was seeing them sitting in cardboard boxes with hay to pee and poo, and I left it this way} . I do find some poop in these boxes but since I am not changing hay there every day, it's hard to say how new this poop is. Also, there is not much poop that I find... and I think I find poop at all because I feed critical care. I don't know if he eats hay there or not. I think he does, at least a little bit.
