my walls are like that where the kiddy gate is.....she will lay there and chew but has stopped after I was on her non stop......she liked the bitter stuff 

 and our tiki bar has the corners chewed as well she is pretty good about it now but I think it was bordom......now she chews on her little bones....every time she wuld chew i would give her her bone....now she gets it...every now and again she will slip up and then over goes the bone.
Befoer we got her crate what she is in when we leae now I had a lamp on the table by the window and I went to turn it on one night and it wouldnt and I looked and she chewed the cord all the way through at the base 

 I am just glad that it was a switch light and not active at the time......byt that is what she would go sit on the table and chew while she was looking out the window.....
we just got Gidget a new bone that she LOVES it is little and pink and smells like mint but it is gooshy so it is like a teether and she just loves it.....even thought she isnt teething....I think it releaves stress (what stress you have from playing and eating and sleeping I dont know :P)
