Boat capsizing?

Well, I've been wondering about Andre's behavior for a few days now. He's back to eating every blade of grass that he passes and taking a loooong time to do all his business in the mornings.

These can both be chalked up to two things. One is that the grass is getting tall, and whenever the grass gets tall, they all eat more. 

Also, I've been pressed for time in the mornings, and since he can't be outside unsupervised, as soon as he's finished he comes inside with me. I may very well have trained him that pottying means going back inside. 

However, he just threw up. A full, food filled vomit. No lethargy, nothing weird behaviorally. And he (sorry for the details) ate it after he chucked it, so it wasn't rotten food. When it's been a blockage, he never eats it. 

We've recently added salmon oil back to his diet. He did have the one incidence of bile prior to the salmon oil, but I think that was a one-off. The last time he threw up for real and had liquid diarrhea, it was after we had started to give him salmon oil (and increased the chicken fat in his diet, so we need to isolate what's triggering things). 

Oh yeah. And this morning's stool was mucus covered. We are worming everyone now, so we'll see what happens. 

The plan going forward is to back off the salmon oil, finish the worming treatments, and see if he stabilizes. Another vomiting incident, though, and we go in for testing. I don't want to spend a ton of time figuring this out while he loses weight or is miserable.
