I know I had at least one shot as a baby/child/whenever it was appropriate in the 70’s. Then the Air Force gave me the MMR vax before deploying in the '00s just for good measure. Much appreciated now.

So? cheap labor?!

That’s the same argument I use for not having kids.

Also, I have a dog.

Yes and, you missed the last crucial step

“Make noise = human pay attention” “Human feeds and protects me = more kittens that probably know to pay attention” … “Profit”
