Mrrrp?
To anyone else in the Cahill universe, the high-pitched sound of the pet Egyptian Mau had a hundred different meanings: the playful mrrp, the I-want-red-snapper mrrp, the that-wasn't-enough-red-snapper mrrp, the thank-you-for-the-meager-portion-of-red-snapper mrrp. And on and on.
But to Ian Kabra's ears, each was the I-hate-you-with-all-my-soul mrrp.
