Amazing what enough TLC will do for a scruffy-looking cat! Years ago I took a stray off the streets. Because she was a long-hair, her coat was quite unkempt, so I named her Ragamuffin. Too bad I don't have any pictures of her when I first found her, but after getting a few good brushings she was a very different cat. Gorgeous - and pregnant.
It's properly called duck tape because it's waterproof. No self-respecting handyman (or handywoman) would EVER use this on ducts - the heat makes the tape become brittle and lose its stickiness.
