Mine tries to take off my acrylic nails, when I get them - he knows they're not REALLY me!
Also, whenever I have had anything on my body bandaged, both Gregor and Gus have tried to "break me out" of my bandages. (I am, of course, flattered, because I know that if THEY had bandages, they would consider it a supreme act of love if I removed the annoying wrappings.)
How long are the dreadlocks? Getting shorter because of nibbling?
