Why Cats Eat Grass: The Natural Behavior Explained

Trigg, my blue Lynx mitted Ragdoll cat, likes to eat grass.  Well, it’s not really grass – but grassy plants that I have in the back corner of my yard.  It is his habit to do this – he does it every time we go outside.   I stopped using chemicals on my lawn about 2 years ago, so I know he is safe in that regard.  I also have heard that it can help with digestion.  Does anyone else know why he might be attracted to eating it?  And also, does your kitty eat grass?
