Yup, my Kalani LOVES plastic - blinds, mats, moldings - if it's plastic he will eat it
I put up a low x-pen (extended) in front of my front door and my front windows to block them from running out and also to keep him from nibbling my blinds. I've tried the bitter apple spray, the clear deodorant, ammonia, etc., and none of it worked. I can't wait till he outgrows this stage so I can stop living in an x-pen - LOL!
