Sounds like some these things could easily be resolved…like the laundry for instance I only fold laundry in my bedroom with the door closed. If I need to be with the Bs because they can't be left alone then I fold laundry in the living room & put them in the expen (not the crate) so they can still move around and be "with mommy" but not into my stuff.
The exercising on the floor..well guess what YOU may actually be giving him the signal that you WANT to play. For instance when C3 wants to play with Topaz he'll grab a fav toy of hers & drops on the floor & looks at her to see if she's going to play. Sometimes he'll lay on his back with his paws up in the air to see if she'll come to play with him. So again, not his fault if you're sending those signals to him Again if you need to be in the same room with him without him "in your way" than put an expen around him so he can still romp around but stays out of your way.
We have 2 expens one inside the house that is very versatile & can take to any room in the house and one for the outside in the backyard either to close up the yard so they can run around like crazies...sometimes they need to be off leash to burn some energy.
