Product review (5 stars): Even better than expected!
I'm building a vented litter box for my cat, who won't really appreciate it. Because you know, cats are contrary beasties.
I like this because:
1. Clear plastic. Easy to see when it needs cleaning.
2. Sturdy plastic. Not going to tear if you look at it cross-eyed.
3. MADE IN AMERICA!! That means gainful employment for my fellow Americans.

I will buy this again when I do the litter boxes for my friend's cats.
