Looking to identify a television show that I saw a long time ago. I believe the show was from the 80's but may have been even from the late 70's. It involved people living/working on a game preserve or national park in (what I assume is) Africa. I believe it was 2 scientists, with a chimp and, the most unique character, a cross-eyed lion.
The episode/scene that I have stuck in my head is where one of the scientist is trying to improve the lion's eyesight by feeding it carrots.
