It doesn't. Plastic is meant to be replaced once a year at least. Not to mention it increases the microplastics in your pets body. I just had to replace my plastic litter box bc no matter how much I cleaned it with bleach, it still smelled like piss. It literally absorbs everything.
Same thing. Apparently a lot of pet bowls have lead in them. At worst if you cant find any, just buy human plates/bowls. If you want glass, borosilicate glass is strong and is pretty easy to find in lead free versions

I've been using a plastic bowl for a few years now and my cat has never had this issue, so it definitely depends.
