This depends on your cat. Generally, you should divide your pet's daily ration into several portions. The rule of thumb is at least two servings per day.
Because the formulas of different dry and wet foods vary, the recommended rations will vary as well.
When feeding your cat, you should consider their age and health.

An average cat (about four kilograms) needs 40 to 60 grams of dry food per day. Exact feeding recommendations can be found on the packaging of your cat food. In addition, you should keep an eye on your cat's health and activity levels.
Your cat should receive about 50 grams of wet food per kilogram of body weight per day, so a healthy adult cat should receive about 200-300 grams of food per day.
Note that the higher the quality of your cat's food, the less your cat will need.

It is best to use plastic tins, as the material is hygienic and tasteless. An airtight seal ensures that the texture and quality of your product remain unchanged.
Opened wet food should be kept in the fridge. It is best to pack the food in aroma- and air-tight fresh-keeping tins.
If you have bought the product in a resealable bag, this should close tightly so that you can keep the packaging safe, cool and dry.
Make sure you store food out of reach of your cat.

Freshly purchased cat food has an unopened shelf life of several months to years. You can find the best-before date directly on the package or carton.
How long cat food will keep when opened depends on the type of food and how it is stored. Food will keep longer in sealable containers than in open packages.
Once you've opened wet food, you should feed it within two days, because even if you keep it in the fridge, it will lose quality over time and may spoil. If you close the dry food after use, it will keep much longer.

Cat food should have a high moisture content.
Since cats are carnivores by nature, meat should make up the majority of the diet. High-protein and high-fat foods have proven to be optimal.
This should continue to be included:
Taurine
Arginine
Arachidonic acid
Vitamins (especially A and B)
