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?
As food grade stainless steel it’s hard to beat for safety for drinking cold water. But you might want to research YETI in particular in case they have had any issues.
