When being brushed or scratched on his back, Chip will pin his ears back and look behind him at me.
OH!!! And do NOT get metal objects around Chip... he gets ANGRY and attacks them. I have no idea what he has against metal, but if moves just the slightest bit, he's right there growling and biting... my little ankle biter!!
Oh and plungers... he gets angry at plungers too. I had to go buy a new one that had a plastic handle because he got angry at the plunger so much and chewed the wooden handle to where I got splinters the next time I had to use it.
