I love it when my kitties start to run out of food or litter. I adore going to Mud Bay! Why everyone doesn't shop there is beyond me. They only carry dust free litter (dusty litter hurts my lungs so think what it does to the tiny lungs of a cat) and they only carry food that doesn't contain any meat by-products (if you knew what a by-product was you wouldn't give them to your animals).
The staff is very knowledgeable, very helpful, and generally very nice.
