Hello m'dear. Boogie is great at this, she used to sit staring at me until she got my attention and then lay into the correx. There's a very easy solution, I will do my best to describe it. Have you ever seen those sliding plastic document spines? They are about 30cm long - I can pm you a piccy if you don't know what I mean. You can get them in primary colours from all good stationers, I get mine from an independent stationers in farnham. They are about 50p each. You just prize them open and slip them along the correx and it creates a chew-proof bite-proof colour co-ordinated edge. Ta da!
It's probably a bit late now, but when you come to replace the correx, add another inch in height. They seem to be more inclined to chew it if it's at nose level or lower. I have done this trick at the door way and in the hammocked corners as when they laid in the hammocks they just used to lay back and pick at it!
