@ jrkob. Please note, I am not an expert. I just like to do my research and feed my cat as healthy as possible. There is a plethora of natural brands. In my case Naturea is not easy to get in HK. Only 1 online shop has this brand. You should look into brands such as Weruva (made in Thailand but read on their FAQ), Wellness and the list goes on which is stocked by more online pet shops. I would also say its a good idea to have 2 brands on rotation. This brings more variety. And in case you run out of one brand then you can switch to the other one right away. Without having to transition over 7 days period.
@ dontdrink&drive. You are right. For logical reasons one would ask the vet. Here is where it becomes problematic... You will notice that vets in HK have affiliations with the HUGE companies such as HILLS or Purina. Hence, you can buy their products readily at the vets.
These brands promote foods for prevention of different ailments in certain ages of cats i.e. oral care, sensitive skin, hairball control, kidney health etc. which is all good. BUT if you look beyond and see the ingredient list it becomes suspicious. They add potatoes, starch, corn, non identifiable meats, etc. In the long term these foods make your pet more sick. Hence you visit vets more often.... They are promoting food that have negative effects on your pets.
Hence, do your own homework is best. A great read for how to pick your foods. Beware, it does mention that "Natural, Holistic food brands" are simple marketing ploys to get us worried pet owners to fork out more $$$.
