It's quite common for Meseh to patrol the Pridelands but more notably he's asked to chase away any hostile hyenas. They were already a problem, frequently poaching and having an overall resentful and vengeful posture towards pridelanders, situation that can be tracked back to Mohatu's youth. Meseh is big and pretty strong and hyenas prefer to avoid any confrontation with him and retreat. However, from time to time and given the poor conditions of the Elephant Graveyard that the hyenas claimed as their home, he will let parents with young cubs drink from the streams and pools. He never befriends any hyena and ultimately they are still a danger to his kind, but has a better understanding of them than the rest of the pride. After some bad things happen (gasp) to the royal cubs (gasp) where hyenas were involved, Ahadi gives the order to attack any hyena at sight, law that remains until Mufasa's reign. Meseh tries to discuss the law with Ahadi but (gasp) Ahadi lashes out at Meseh for defying him, to Meseh's dismay, since this is the first (and last) time Ahadi has made evident his authority over him.

If I have a character that hates hyenas with a passion, those are Ahadi and Hairi (Nala's dad) Hairi has hated hyenas all his life due to his past experiences, while Ahadi developed that hate when his sons were cubs, up until then he was very much neutral to them but that was the breaking point.
