I checked Wild Harvest on Wal Mart's web site. You're right. This rabbit food is not healthy! It's full of junk food. When looking for a good rabbit pellet, read the ingredients on the package. The protein should be no higher than 14% (for an adult), and the fiber should be at least 18%. The higher the fiber, the better. So, you're looking for LOW protein and HIGH fiber. Then look at the list of ingredients. They are listed in the order of how much of that ingredient is in the product. In other words, the first ingredient is the most and the last ingredient is the least. So, the first ingredient should be timothy hay for an adult rabbit and alfalfa for a young rabbit (4 months or younger).
As stated by another person, Oxbow is a good brand. Oxbow Essentials - Young Rabbit is alfalfa based. Oxbow Essentials is Timothy hay based. However, my rabbits don't like Oxbow pellets, either. So, I buy Zupreem Nature's Promise which is sold in Petco. It has 14% protein and 28% fiber. My rabbits love it. I buy several bags online from Petco when it goes on sale, so I get the free shipping and the sale price.
When you switch your rabbit to a better pellet start with mixing the two about 2/3 to 1/3 for a few days. If she's doing okay, go half and half for a few days, etc.
BTW, I use Care Fresh bedding/litter and also buy it in bulk from the Petco site when it's on sale at a substantial savings.
