What I use isn't in there either. I use chicken feed.
All of you Swheat Scoop and "World's Best" lovers need to go check out
this thread. You can get the same performance from chick starter feed that you get from the ridiculously overpriced Swheat Scoop and WBCL. If you do a side-by-side comparison of World's Best and chick starter feed, you will not be able to tell them apart. Well, except for the price!
17lbs. of World's Best- $18.00
14lbs. of Swheat Scoop- $11.00
50lbs. of chick starter feed- $12.00
Yes, I said FIFTY pounds. It replaces about 80lbs. of clumping clay litter, so even if you use the cheapest clumping clay you can find, the chick starter is still cheaper.
