CB pets is a quick drive up 281, exit 46, turn left, in the back corner of the HEB shopping center, it's EASY to find, HEB is the first stop light on 46, can't miss it. I am not sure about any of the other stores, I haven't been to them in a while, CB Pets is closest to me, and they order everything I want, so I really have no need to go elsewhere. they actually have quite the selection of reef janitors right now.
