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?
The Yeti cups I have are stainless steel which I consider safe. Food processing facilities I’m familiar with (liquids like dairy, breweries, etc) use stainless steel plumbing everywhere. It’s relatively inert and can be sanitized.
Aluminum, like pop cans actually has a plastic liner inside which probably isn’t great. Seems like opinions on aluminum cookware shift from time to time. I just stick with stainless or cast iron so I’m not sure what the current thought on aluminum is.
