Spencer: Those are just other index cards taped on. I am going to look for something a little more durable if these start falling apart. But they sould work for now.

Emily: I keep Excel files full of all the info and when they fill up I print them out and store them in a folder. My problem was ....the mess of opening all the files and editing them while I was walking to and from the computer and feeding/cleaning etc.....I figured I would use the cards and just transfer info when they fill up...then toss the cards to save space
