Exactly. I can excuse Solembum doing that in a panic, because he was in a lot of pain and his ear was missing, and then he sees Eragon about to get eaten. And it would be dangerous to try to get the Ra'zac away without getting even more injured. Also, he's a cat. They don't tend to do non-lethal pouncing. But the second one has no excuse. Also, it makes no sense why the priests just left. I know it's because of the plot, but if I was guarding a god, I would damn well make sure no harm could come to said god.
