what are the behavioral patterns of the meekats? how do they react to pi and richard parker?

The meerkats pull fish out of the water and sleep in trees. Both Pi and Richard Parker manage to revive themselves, Pi with the algae, Richard Parker with the meerkats, and both with the fresh water and exercise. Richard Parker starts to get more aggressive, so Pi goes back to training him. Pi discovers that the ground is acidic at night hence the Meerkats refuge to the trees.
