animals have insticts to feel danger

Can you tell me if this is how an English speaker will say the 2 sentences?

If animals have super instincts to feel danger coming, I have nothing to worry about, my dog is slumped on the couch. Tomorrow mustn't be the end of the world.

Animals seem to have a instinct that danger is at their door. We had several cats exhibit signs of restlessness as they grew closer to death.
