my cat, Binka (where i got my user name), sleeps in some of the weirdest positions you'll ever see. somewhere, i have a picture where she fell asleep, aparently right after cleaning her bottom. you know, where cats lift up their leg to clean there. well, in the pic, she looks like she's doing yoga in her sleep. she all has her back leg behind her head while she's fast asleep.
i have another cat, Mimi, who often sit like a seal. really! she looks like a seal half the time! she also runs in circles around my feet everytime i'm holding a plate or bowl. she thinks that whatever food i have, it's for her, too.
