Allen never really purred until recently - after we got Pouncer. He only purrs when he's sleeping and you pet him. Pouncer purrs often and for no obvious reason. Now that he's a bit older, he's been purring a little less often than beofre. At 3.5 months, all you had to do was put your hand on him and he'd start purring. I don't know why they change their purring habits. I guess it is like us - we all find different thing to make us laugh, smile, sigh, etc.

By the way, I'm glad to see you back... I was wondering where you went and how the babeis were doing!
