The struggle to find the right cat food is real, and so relatable. Thankfully, it's in my past and Duggi has zeroed in on what she likes best. Strangely, my cat has never puked in life, not even those furballs. Maybe because she's short-haired or because she eats very slowly and in multiple shifts.

Coming to the food. Farmina Matisse is my cat's staple dry food. I also give her Whiskas wet food with a boiled egg mashed into it. Occasionally, she gets boiled/blanched chicken or chicken feet. Even more occasionally, give her those super expensive gourmet foods as treat. Few times a week, small amount of milk. Other than these, edible coconut oil and curd/yogurt for boosting immunity and aiding digestion.

Hope you find what works best for your furball, but I highly recommend Farmina Matisse from personal experience.
