Still, that's pretty impressive. Cats are absolutely incredible animals. I'm thankful the "worst behaved cats" still love me for whatever reason because I've been able to see some of the crazy shit they do.

My parents have an entirely blind 18 year old cat. She can navigate the entire house eats fine, plays a bit. Hops up and down furniture, finds the sunbathing spots, uses the litter just fine. You do have to keep an eye out for her if your moving around as she can't smell fast enough if you step in front of her path.
