I have been reading different opinions about cleaning the litter box, bedding, and house after your cat has roundworms. But there doesn't seem to be a consensus on what actually works and many of the cleaning steps are extremely labor intensive. Is it really necessary to clean more than regularly scooping the litter if your cat has worms and has been dewormed and is now on a monthly preventative? If so, what specific steps would you recommend?

Definitely make sure to treat all four of them for worms, and give them a second deworming treatment after the first one. That's because it will take at least two rounds of treatment in order to kill all the worms. The first kills the adults present at the time of the first deworming, and the second kills the adults who had not yet hatched at the time of the first treatment. After that, they should all be dewormed every three months. Yes, I would clean the house as well, give it a really good scrub, especially the floors and litter box. Be sure to wear gloves when cleaning the litter box, and practice good hygiene. I recommend using Panacur, it's an excellent deworming treatment.
