I cat sat once for a friend who had a plastic goblin. I spent the entire two weeks obsessively checking that I didn't leave any plastic out only to (occasionally) find the cat happily chewing on something that I didn't think they would find.
I learned my lesson about the depths of feline creativity lol and I was thankful they didn't get into anything that hurt them
She doesn't even like to chew plastic. She will just sit there and lick plastic bins.
Copying humans, they feel they need more microplastics
