Thanks to Larren_Chen, khairi, lemonlogix and especially Azure for your kind comments.
Azure,
You were right beside me when that "yawning" sequence was taken. So you know how lucky and instinctive a photographer needs to be. Never mind too much about the slight tilt. Once a yawn begins, just let the motor drive get to work !
My own gripe about the shot is that the feline has a blue plastic string at its neck. Now, that is not photogenic, and probably cruel as well.
Thanks once again.
