I have two cats that are both crazy for their own reasons.
One is just in love with marshmallows. He will not eat them that much, but loves to bite and kick them. I think, he just loves the texture of that. He also love to lick every sweet there is. We have to keep him away from glasses with fountain drinks, because he will lick edges.
Second one just loves plastic. When he is hungry, he will not look for food, but for plastic to chew instead. Any plastic bag, ribbon, anything, he will munch that until he will choke… Twice I had to pull a present ribbon from his throat… It’s especially hard on Christmas 😃
