Maybe if the cats are too upset they can put the baby up for adoption.
;-)

CERTAINLY this is the time (if you do not already) to keep the cats claws
trimmed short so as to minimize scratch wounds inflicted upon the infant.

Babies come first.  Any cat that doesn't adjust or becomes aggressive more
than once is a cat you cannot have in the house.

Sorry, had to laugh. My own cats have suddenly got a crawling baby too, int
he last 6 months. Shmogg flatly refuses to be in the same room as him, quite
wise I think. But IBKFergus thinks Cary is just great. Not only does he move
around on all fours, like a cat, he is always trying to scavenge food
(everything goes in the mouth whether food or otherwise) and he makes weird
babbling and chittering noises like a cat. He also plays ball with her, and
they share a favourite toy (a tailless mousie that rattles). She's pretty
horrified about his lack of litterbox skills, but on the whole thinks Cary
is a Good Thing. Except when he's sucking her tail, of course.

Fluffy (D*g) has also realised that Cary comes with a halo of food around
his person, but is unsure whether ear-sucking is a pleasurable activity or
not. Mostly, she just looks at me with those big doleful brown eyes with a
"why me?" expression on her face. Still, in a year or so when Cary can run
and throw balls a bit better, I think Fluff and Cary will be the very
bestest of best friends.
