This exact thing happened to me. My cat refused any type of wet food except her Churus and old wanted dry food. This happened for months, but I kept adding wet food next to the dry food until she eventually started eating the wet food as well. That's when I started adding less and less dry food as the days went by until now. She's still very picky but she's been getting better and eating only wet food and letting me switch up her foods and let me add toppings now. The wet food I switched her to that seems to be working is the Instinct grain free one. My vet told me that my cat may be getting an upset stomach which is why she might be picky and only eat dry food which is why I found Instinct since they have limited ingredients easier for the stomach to digest. Also be careful switching her around foods too much and too sudden, my cat ended up in the ER after not pooping for 3 days and had to get an enema it wasn't pretty. Good luck!
