In many parts of the world, marijuana is now legal to use for medicinal and recreational purposes. In the feline world, there’s a different type of grass that kitties seem to enjoy.
By chewing on grass and then throwing it up afterwards, cats seem to love grass. One theory says that cats eat grass to throw up the indigestible parts of their prey such as birds or mice. Other theories claim cats eat grass as a laxative.
Whatever the case, you may want to grow your own cat grass to that way your cats can eat grass without going outside. Then again, why would you buy something that would encourage your cat to vomit on the floor, unless, of course, you enjoy cleaning up after your pet on a regular basis.
