Marco the alpaca died this afternoon. I took him to the vet's office for a necropsy. The report came back that the dewormer did do the trick, but that Marco had no fat around his internal organs. So, basically, he was too far gone for regular treatment once his external symptoms showed up.
I'm not heartbroken, just... blue. And annoyed with myself. I feel like a bad farm-mom yet again. Why the hell to I have so much trouble seeing body-condition problems?
Comparatively, our llama is doing just fine. He isn't skinny, isn't scouring, isn't off of his feed, or anything else by which we might judge him as being sick. Marco was a rescue; Herc came from a good farm and a good family. And there's that whole fragile-alpaca vs. butch llama thing going too.
