Your infested crew is adorable.

Use a dry swiffer to pick up dust on your hardwoods, and vacuum along baseboards and in corners, and underneath everything. Vacuum furniture and drapes. Wash everything that is washable. Hopefully you did catch it early, so you are ahead of the game.
I worked in an office with a woman who was a cat hoarder and her house had a terrible flea infestation. She was carrying the fleas into the office on her clothes and purse.
Vacuum and clean every nook and cranny.
