So I’ve got a new cat. He likes to drink out of people glasses instead of his bowl. After giving up on keeping him away from my glassware I went through the pantry and found an old YETI cup with a good lid to keep him out of my water. I think its either aluminum or stainless steel but there are no markings to indicate. Is this safe or am I slowly giving myself heavy metal poisoning?
is it an actual YETI brand? If so, no problem. Stainless steel is an excellent drinking vessel. It’s either 18-8/304 or 316 but doubtful 316. As long as you aren’t storing acidic foods in it like your grandmas marinara sauce, it should be fine. Stainless can potentially leach nickel and chromium but it requires either poor quality stainless steel or something acidic. Same concept as not storing acidic stuff in the can it was sold in, once opened.
