My cat is obsessed with elastic bands. Not loose ones, ones that are one stuff.
Like on my library books, there is always a rubber band holding the paper with my library card # on it (holds).
She likes to lift it up with her teeth and let it snap back down.
She will do it for literally hours.
She does it with my son's wrestling ring toy too, it has elastic "ropes" that she is constantly "twanging". Recently I bought ds his new winter boots and she has been twanging the elastic that holds the boots together.
lol weird cat.
What are your cat's weird habits?
