That's about the same price as Pet Food Direct on the web. Hopefully Petco will sell them or I can find somewhere that will sell them.
It's good the girls don't like Lamb, at least that's a plus for Jasper. He can have his food to himself. I saw a brand at the specialty pet store called Wysong. I didn't have a chance to look at the ingredients, but all they sell at this place is the good high quality brands so maybe that is something you can look into.
