Well I am cheap. I was reading a while back on cat litter. My kitty, eco terrorist that he is, has decided he likes feline pine kitty litter. That's okay by me, but that stuff is expensive. I was reading on a blog, I believe "fake plastic fish", on one of her cat litter posts, some of her readers use Pellet stove pellets. They look the same as Feline Pine, act the same, both turn to sawdust when pee'd on. So I price a 40 pound sack- $5.49 at the Grocery store, same price as a 10 pound bag of Feline Pine roughly $1.40 for the same amount. So I thought "Why not- if Sammy Cat likes it then I am money ahead". I bought the pellets. I changed his litter tonight. And he is using it. Yea Sammy! He knows there is tuna or better yet Sardines in his future for saving me money.
