From a certain male perspective.
First, I'd store animal food outside so it would not draw mice and roaches in the house, but I know I'm weird. And, if I transfer feed from one container or bag to another, I do it in a place that a spill is not a big deal. Something will clean it up and it won't be me.
However, more to your question, if I make a mess I clean it up. If she makes a mess, I get out of the way. When I spill something in the kitchen, depending what it is, I sweep it up. Yes, I know where the broom and dust pan are. I may vacuum it up, using my wet-dry shop vac instead of her household vacuum. I will not mop it up as my wife got rid of the old basic cotton mop and has about three different special kinds of mops and I find that none of them are good for actually mopping. Instead, we keep pieces of old tee shirts which can go into the laundry for cleaning up messes, instead of using paper towels. I try to do a pretty decent job of cleaning up my own messes, but I'd also realize that nothing I do will meet her cleanliness standards, unless of course she does not know I made the mess to start with. Then she will never notice.
Have a nice day!!!
