Can a cat have an allergy to a certain food, like beef, even before they ever eat it? Or is it, for a cat to have an allergy to a certain protein they have to develop one over time?
I just heard that beef is a common allergen for cats and wonder since my cat seems sensitive to certain foods (chicken) if it would be ok to give him it if he has never had it before.
