Catlady,

I have a cat, Doogie, who is just over a year as well who likes to chew, mostly stuff made of plastic such as pens, combs, my cell phone antenna, etc.

I finally got him some of those dog chew sticks. He chews them for a while then gets bored with them.

I'd ask your vet just out of curiosity. Let me know what he says cuz I have NO clue why they do it.

As far as chewing wires, be very careful!! You might try covering the wires with aluminum foil. They don't like that. Don't want him getting zapped.
