If you ever encounter Ezri in this position, please attempt to scratch her belly. She'll curl in a ball around your hand and deliver a gentle nip. Then her face will light up as if to say, "In biting you I have sated my primal need to taste flesh. Now I'm free to go back to eating elastic bands! AND NAPPING. Good times!"
Until last week I was despairing about Ezri not losing weight despite her new/expensive diet food. Klaxon responded by developing an exercise program for her. If we are walking somewhere and we pass Ezri, we pick her up and carry her to a different location. The idea being that she will walk back to her previous location (usually the chesterfield or my bed). Ezri doesn't know that we are trying to make her exercise, she thinks we are attempting to diversify her nap locations. Upon being set down, she is quite happy to puddle on the floor and sleep for several hours before getting up, walking to the back hall and showing off her new/only trick: prying open the lid to her food container and having a snack.
Good job, Ezri, your sizable rump is no longer making your head look like a grape!
