Hey man...you can scrap the cats if there is no one interested instead of throwing them in the trash. My friend got a couple of bucks when he got rid of his at a local scrap yard. Just a search on the internet shows there are other facilities that will pay for your old cats and ship them for free. I've never used this service, but used cats are worth something..just an fyi.
