I’m speculating here but your cat could be seeing your preparation as assurance that the food is safe for her to eat. By instinct, cats tend to be picky eaters out of concern for eating spoiled food that could result in serious illness. Cats are not scavengers and don’t have the digestive system and metabolism for food that is not fresh. I think cats in colonies may behave the same way with each other to keep themselves safe. If my thought is correct, your cat is trusting your judgement and she may feel okay putting her life in your hands. This could be symbolic of a very strong bond. 😻
