When feeding Timothy hay pellets, look for high fiber (18% or more) and low protein (14% or less) and no junk food in it, ie, dried apple, carrots, seeds, etc. Just the pellets, nothing else. Also, check the ingredients list and make sure the FIRST thing listed is Timothy hay, not alfalfa (for an adult rabbit), not Timothy middlings (this is floor sweepings), and not wheat middlings. For example, Oxbow Adult Rabbit Food information is as follows, notice the first 3 ingredients are grasses. The amount of the ingredient goes from most to least, so it has more Timothy grass than anything else and the least is Calcium Iodate (I've no idea what that is). But, basically, high fiber, low protein, and no junk food.
