Hi! I'm having trouble gauging if my bun is eating enough hay to where it consists of 80% of his diet. Right now (4 months old) he gets about 1/4 cup of pellets in the morning and at night, and 1-2 cups of veggies in the evening. He eats hay fairly consistently throughout the day (timothy, oat, organic meadow), but how can I tell how much is 80%? For instance, how much is a 5" strand of timothy hay in comparison to pellets? Hope this question makes sense. I think that he is eating enough of it where its not an issue, but I want to ensure that his diet is the best it can be.
