Cod, have you read Louise Rennison's Georgia books? (Possibly, not as you have young boys.) Because there's a cool cat in the books by the name of Angus (and not forgetting Naomi-the-Burmese-sex-kitten!). I'm thinking your kitten might be Angus incarnate. Angus is half Scottish wildcat and acts appropriately. The first book is coming out on film this summer - Angus, Thongs and Full Frontal Snogging(!!).
