Self-cleaning litter boxes are beneficial for your cat if your cat is young and healthy. Potty training a cat with a litter box is really an excellent option as it teaches the kitten the proper potty habits as no one likes to destroy their bedsheet and sofa. My cat usually eats litter from the litter box and that's not hygienic and good for her health. To control that I decided to divert her attention by keeping my kitty busy in playing or by buying some toys for her and food puzzles also. You can train your cat whenever you spot a cat eating litter by dragging her attention toward you. However, it will take time; slowly, your cat will understand that it shouldn’t eat litter.
