We have a cat who hates everyone except DH and I (with us, he's the most affectionate, needy cat on earth), and relatives and friends had expressed their worry that the cat would bite and scratch once the baby was home. I had a feeling though that the cat would be the exact opposite - would see DS as a new addition to his territory, and therefore someone else to love and protect fiercely.
I'm happy to report this is exactly how things have played out. From the moment we brought DS home last Friday, the cat has appointed himself almost a nursemaid and guard. He sits by us during feedings, sniffs DS's head gently, peers into the bassinet or crib as if checking up on him, and otherwise seems like he considers it his duty to make sure LO stays safe.
Hope other cat mama's are having equally positive stories!
