Maverick did fine last night and so far nothing this morning. I'm waiting for him to poop so I can check his poop out. But he is acting fine and slept all through the night with no problems. I, of course, did not sleep so well b/c I was worried about him. I don't think it's the cat food that was/is making him sick b/c he hasn't had any in a week really. And since last week he had ate it pretty regularly when it was down and I didn't catch him. We don't have any plants around the house so it couldn't be that. So I'm just going to watch him today and see how he does and see if I can get him into the vet. Again thanks for the advice and good thoughts.
Also, when I said field I didn't mean he was farming. I guess I got a little confused there when I replied up above. He is a Marine and sometimes they go out in the "field" to do things. Brush up on their training and all that. I call it a little "camping trip" So that's what I meant there. He's not a farmer!
