What if you just changed the pillowcase? Since it was the only part exposed that the cat could have walked on, it seems like only thw pillow could be contaminated.

I doubt your cat walked through the v though. Cats hate to get dirty. And as for her stepping on the pavement, I am sure if your catis lik mine she grooms herslf like crazy so she is probably very clean and any particles are long since cleared away.

Plus even if the v is not drunken v, it could be from any number of other sources- a pregnant woman, someone who gets motion sick, even a kid who ate too much candy or sometjing.

I hope you get som rest tonight
