As far as I know friskies is the only one alum. I have been saving them for about a year. I noticed it one day when I got a few bags full of tin cans. I have several ppl save their cans for me, I get several bags full, and when I have nothing else better to do, I crush them to save room. 50 gallon black bag of crushed tin cans weigh about 30-40 lbs. I don't have to peel lables off or anything. One day I noticed some was crushing easier than others, (friskies vs nine lives) looking farther I realized friskies was alum. I do peel the lable off them and make sure they are clean. I get can price for them. They put them in the bale just like beer/pop cans.
