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?
I do think that its a cleanliness thing. The cat is new to me but he was my mom’s cat for like 12 years. He started doing it when they had a dog, we think to avoid backwash. They tried a cat fountain but he wasn’t interested. He also likes the glasses to be up on a table or something instead of the floor and I don’t want a fountain running continuously on my desk.
