Poor old Cassie and Sirius have become more or less reconciled to Grandson. He really likes them and will trot up to them, say HELLO PUSSY!!!! in ringing tones and giggle loudly - and on the whole they stand (sit) their ground. They allow him to pat them (usually) and don't flinch too much when he seizes a tail and tickles his nose with it, chortling away.
They're pleased that that the worst of this baby nonsense is over.
