So you’re saying I should’ve eaten the cat that lived in my apartment when I was a baby?

It's possible that if you had more cat dander in your mouth when you were a baby that you wouldn't have developed an allergy. Or, more likely, if you had more mouth exposure to other natural microbes that occur outdoors and around animals, then you would have fewer allergies overall. That is well supported by the evidence.
