Cat Grass

关于

Why do cats like to eat grass? As with many of the things that cats do, we don't really know. It's believed the grass is good for their digestive systems, encouraging them to pass or expel hairballs and indigestible bits of the creatures they've preyed upon. It also contains trace vitamins and minerals they may be craving. Regardless, varieties of grasses approved for feline use are beneficial for kitty bellies, and if nothing else, they seem to genuinely enjoy chowing down on it.
