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?
yeti is most likely to be food-grade stainless steel, i think you will be fine with this.
