The specific types of grass eaten by each animal vary depending on their size, diet, and habitat. For example, cows graze on large quantities of grass, while rabbits prefer to nibble on smaller blades. Some animals, such as deer and elk, are known to browse on both grasses and other plants.

It's important to note that some animals may be more selective about the types of grass they eat, while others will consume any available grass.
