Cats on surfaces are no worse than not washing hands after a nappy change.
Surfaces can be easily cleaned, unless you have clutter. if you have a kitchen door, it can be closed.
Anything a cat might like (cheese, butter etc.) or food, put away after use, as is poison (chocolate, cleaning fluids).
As for tables, we clean ours before eating, it is clear of clutter, so is very easy to do. We do have a house with rooms and doors though, not one of those that is devoid of architectural features and useful bits like walls and doors as is the fashion these days.
Cats are inquisitive, they jump and climb. I would also sanitise my house after a child invasion, nose picking, playing in allsorts outdoors, fiddling with nappies, willies etc. and climbing on furniture.
What about people who put their shopping bags on the work surfaces after putting them on floors and pavements and then prepare food on said surfaces without cleaning them?
