In the weeks prior to Jack's haircut, he had looked pretty pathetic. He spent all day laying around the apartment like in the photo above, except with his arms stretched out as far as they would go above his head, probably in an effort to air his body out in the heat. He was coughing up a bunch of hairballs and pretty much just miserable, so I finally took him in for a grooming.
Now he sits around the apartment in normal cat positions, and seems pretty happy. Occasionally, he still likes to lay on his back and stretch out, and now it's even cuter:
The only downside of having him groomed is that I think he get's confused more often about his tail. He chases it all the time and tries to bite it - I guess he doesn't recognize his own self!
