I so agree with your comments Sarah.
The cats available are laughable, if it was in the least bit funny, that is, which it isn't.
When I'm listing something that doesn't have a proper category, I too stick it into something that is close enough to warrant that it doesn't get poofed into cyber space because it's in the wrong cat.
TBH, I don't bother anymore asking for another cat to be added, I have neither the time nor patience to wait 6 months or longer for my request to be acknowledged.
