I have looked everywhere and I can find whisker nor tail of her. My friend Croon came over and did some fancy-pants wire-mapping thing to see if she could see her, but that yielded nothing, either. I tried a bit of reverse-psychology and pretended that I didn't care that my cat had gone AWOL, and she still hasn't come back. She isn't in my lost and found folder (a folder that basically does what it says on the tin, non-SL users). I cannot find her anywhere.
If you have any suggestions as to where she might be and/or how to find her, please let me know! I'm using the official Linden Labs viewer, with the latest update, if that helps!
