Is there anything at all I can do to cut down on the shedding?

of cat fur flying around, it's everywhere

What's the best vacuum for pet fur?

I really love the Furminator brush. It works great and gets the hair
out. You do need to use it at least once a week to fully cut down on
the shedding. I prefer a small shop vac for removing pet hair, or for
smaller areas a yellow Gonzo sponge (you can get at a pet store) that
you wipe across the fur.

As for their diet, I think a change to a premium wet food would help
them. I have two cats who are fed premium wet food and while I have
some shedding, it's nothing like you arre describing.
