My cat is 2 (3?) years old. He started to take plastic baggies and anything plastic and chew on them. It gets so bad some nights I wake up hearing him choking on plastic. He also gnaws at USB cords. For a year I thought he was biting at them chewing them up, but the ipod cord which is his favorite, he hasn't actually bitten through it anywhere. I can see gentle puncture marks but it looks like he's trying to just get the wire between his teeth and chomp down on it rather than bite it directly and chew it up.
So if he's trying to cram the plastic cord between his teeth, this is what I assume he's also doing with plastic baggies, is there an issue with his gums? Maybe his teeth hurt and this relieves pain? I ignored this behavior as a kitten because I thought he was just teething, but now I'm getting tired of yelling at him every minute to get away from the garbage can. He knows I punish him and scream NO when he does it, he knows what no means since he runs away every time i scream it at him as he's about to chew something plastic. But once I look away, or even while I'm watching he sneaks up, sniffs it, licks it, and tries to discreetly chew it till I have to go pick him up and carry him away.
