Dan, thanks so much for posting those two links. Only a couple of cat food brands I use are BPA safe. I'll contact the other two to find out.
Regarding the register receipts, well, I thought I found a great use for them. I have oily skin and I found they work great as blotting tissues. Well, no more, because it was the BPA kind that worked well.
We just have to be so aware as consumers.
