serafina, what brand are you feeding?
Serafina really likes Küme (https://www.kume.com.ar/alimento-holistico-gatos/) which is sold in certain pet stores - you have to look on their map to find the closest to you. They just have one type for cats but they have more options for dogs. Originally, it was created by Argentinian veterinarians for dog breeders. This is the cat food I was referring to in my post currently sold for 670 ARS per 1.5kg bag. The price may vary depending on the store where you buy it. I have found differences of up to 80 ARS between stores, which I paid anyway because the supply is limited (apparently, it is very sought after and they can't keep up with the demand), so I buy it whenever I can.
We have tried several premium brands that were launched recently, such as Nutrique (made with turkey, is considered super premium, it is the most expensive of all) which offers 4 cat food: kitten, adult, sterilized and seniors. We tried kitten and adult.
We also tried Mon Ami, also premium. The box contains a number of plastic sealed packets to preserve freshness. She was intrigued by the novelty, but it was a fad for her. Of course, if there is only one food type, she will have it.
But I have bought all three at the same time, and the bowl constantly empty was the one with Küme.
We also bought Ünik in the past, but Serafina the cat was not fond of the brand.
Originally, when we adopted her in 2014 the cat food offer was very limited. I remember seeing some small golden tins of Gourmet (here they were sold under a different name, I think Diamond something...) but they went away in a few months. So Serafina has been brought up on dry food only, and she won't have real food (except some crumbs that reminds her of dry pet food). We fed her Royal Canin and Pro Plan for years, but since we found about the other premium brands, we have tried them all and the verdict is: Küme.
I tried several brands to break the routine throughout the years. I have always given her two types of food at the same time since here you cannot pick flavors (i.e. chicken, meat, turkey, fish) to rpovide some variety.
