Chance - loves to play with any running water and burrow under the covers at night.
Pebbles - we have always said is not right in the head. She will be standing next to you one minute, then jump straight up in the air for no reason, fly into the other room and sail to the top of the cat condo doing about 100mph. It's almost like a switch in her brain clicks on and off she goes. She's also just plain moody. Sometimes there isn't even anyone remotely close to her and she'll start hissing, or she'll coax Chance into playing with her only to turn around 5 minutes later and take him out with a swat and hiss. She's made it clear she doesn't like him, yet she eggs him on to play with her then is mean to him. Moody little you-know-what. My daughters call her our "EMO Cat" (that's the term teenagers use these days for someone who is very emotional)
Snickers - is so curious she loves to watch what's going on all the time, but is too scared to get close so she sits around corners and will just peek her head around the corner to watch what's happening. It's so cute!
Peanut - has to drink running tap water only and will paw at the sink and scream at the top of her lungs in the bathroom until one of us goes and turns the water on. Peanut also brings me laundry - everyday, all day - socks, underwear, t-shirts, etc and delivers them to various parts of the house. She also has spent a great deal of time in my tree this year!
Zoey - no quirks - she's too "proper" and too much of a princess to be anything but elegant (or so she thinks).
When it comes down to it - Pebbles and Peanut are my terrors and I think they have the most quirks.
