I'll be curious if anyone else has suggestions/experiences, but I'm happy to share mine for now.
I have three cats, and I was surprised to find that it was a total non-issue. The first few weeks, I did lock the cats out of my room at night - it was a pain, but I couldn't sleep well, worrying about the cats possibly jumping into the bassinet. However, my cats are sort of freaked out by DD, so they've never wanted to really be anywhere near her. It's only now that 2 of them are even allowing her to come near enough to pet them. And these were cats that loved trying to sleep in the crib, bassinet, stroller, and the diaper changing pad before DD arrived.
Maybe put the cat food in the kitchen and the litter box in a guest bath for the first few weeks, until you see how the cats react to the baby. My guess is they will want nothing to do with the new little human, and you can all return to your old routine quickly.
