When I was out shopping one day I found a display table outside of a store that had a cute little item for cats on sale…a small crate made out of wood, painted with little kitties, which was to be used as a planter…inside was a package of dirt and a smaller packet of something called Cosmic Kitty Herbs….they statement on the package, which really caught my eye, was that it was a product that would prevent hairballs in cats, just plant the seeds, let them grow and the cats would do the rest…besides that, the roughage of the grass would also help them internally….as a bonus it was a healthy treat providing natural herbs and vitamins
I have 3 indoor cats and at that time one of them had a real hairball problem, he was a long haired big boy and I found little "gifts" from him on …
