Whenever you are shooting animals, always focus on the eyes. 1 and 2 would of been better. You could of also increased your depth-of-field and got more in focus.
Focus on the eyes. Turn off your flash. Re-shoot with natural light. Google 'using window light in photography' Shooting animals can be very difficult, but your composition could use some work. You have a lot of stuff (couch,floor) that is not really adding to the picture. Either crop or re-compose the shot. #2 focus is on the nose, not on the eyes and you cropped part of the head. Keep on practicing, you'll get better in no time.
