Should the brand of cat food be fixed or changed?

Non-professionals, just talk about personal opinions.

I don't know if your cat is a kind of cat with a glass stomach, but mine is.

I don't often change his food. I will choose a brand of cat food/canned food within the range I think fit, and then I will die.

If you change food frequently. First of all, cats may not eat, which is an economic loss to their owners; Secondly, cats with soft stools may be uncomfortable. What I fear most is that cats are soft and furry, and they can paste everywhere. Finally, it may raise the cat's mouth.

If you don't change the granules all the time, there will be problems. Is the nutrition balanced?

In this regard, my solution is that cat food is only the foundation, and I will feed it in cans; Buy cans of the same brand with several flavors and eat as much meat as possible; Nutritional cream and goat milk powder at home are always available; Occasionally homemade, ingredients include: chicken breast, beef, fish, prawns.

In short, I haven't been so careful in eating by myself. If the nutrition is not balanced, what makes me feel sorry?
