How do I clean a cat throw up stain on laminate flooring?

It's acidic, so I would say yes if you don't get it cleaned up.

I don't have cats but I imagine there's a lot of stomach acid included which would not be good for any surface.

Laminate floor is pretty strong! I would say it depends on the color of the floor and how long the vomit sits.

It will eat the finish off of most surfaces just as any vomit would

We have many indoor cats and they some are prone to vomiting on the blonde laminate flooring in the kitchen and bathroom. It has never left a stain nor damaged the floor in any way.
