Grass is the most natural food for rabbits although hay is a perfect substitute, some rabbits may go their whole life without ever tasting fresh grass. So why not grow your own grass and treat your bunnies. It’s best to introduce grass slowly, since a sudden change in diet can cause digestive problems in rabbits. #indoorbunny #freshgrass #rabbitsofinstagram #bunniesofinstagram #rabbitcare #petbunny #rabbitdiet #bunnyenrichment
