Thanks Karey. While I've been informed they eat cheese, I haven't been able to clarify whether that includes cheeses made with animal retin (which are the normal cheeses).
I'm also looking at stuff that contains high level of protein, so I'm guessing I'm looking at nuts and Neil's favourite "lentils".
I thought the t-rex's closest modern relative was the sparrow?
Yes, I tend to agree caps. Cattle are simply sources of grass made edible and what not.
