Yes they will follow you, they love to beg, if your lion is young, you can feed a small chunk daily, if your lion is not to young try feeding a small chunk every other day, you can feed until there is a slight bulge in the stomach area. As your lion matures you can feed every 2-3 days.
Your lion needs a variety of food soaked in vitamins, you can pick up a feeder stick from your LFS, try feeding Raw Shrimp, Crab, Scallops, frozen sand eels and so on.
Lions love to beg but do not over feed it is not healthy for your lion, lions are Non-aggressive Predators.
