Here's a better picture of our new cat. We've pretty much decided on the name Igmutonka (Mountain Lion or Great/Large Cat in Sioux). Though she'll probably end up with several nicknames, like the other animals we have owned. ChubChub seems to be my husband's favorite.
You can see in this photo how truly fat she is. We're actually getting a step for her so she can get up on the bed herself. She can manage the couch, but the bed is too high.

She is adorable. I have a very fat cat too. We adopted her from a shelter as well but we kept her original name, Kahlua!
Sadia's not big enough that we're at all concerned about her weight. Her only problem is that she's very small and a little heavy so sometimes she'll have to try a jump more than once to chase her thinner, leaner sisters around the house. She can get onto the bed but sometimes it's a jump, grab and pull sort of event. Thank goodness for Softpaws! (Of course, other times she'll just stair at the windowsill and offer a pitiful meow as someone walks by. The human elevators are usually forthcoming.)
