I Nearly Fell Over!

Yesterday afternoon I was walking with my 4yo daughter when a white cat ran across our path.
F, the 4yo said to me "Mommy, I want a white cat" at which time I gave there the regular answer about family with allergies.
She then told me she would be happy with that cat.
So I explained the cat we had just seen was likely ferrel.

Her response? "My daddy eats ferrel cats."
As if it was the most normal thing in the world.
There is no appropriate response to that.
