How Prophet Noah (AS) manages the animals on the ark?

Assalam O Alaikum! I'm very keen to know how Prophet Noah (AS) manages the animals on his ark? Because the lion's fitra (Nature) is kind of beast animal so he can harm humans or animals like goats and sheeps. > I want to clarify that by saying LION I mean beat animals. They could > be anything since I don't know which kind of animals did Nuh AS take > with Him. So is it Allah (SWT) who make lion's heart soft?
