Cat wants only wet food, is this harmful?

Especially for cats that consume very little water and therefore have problems with constipation and kidney disease, the water content in wet food is very important.

Wet food is also very popular because it can be stored in sealed food cans for a very long time. Wet food cans can be stored for up to several years. If the food can is already opened, you can close it with the help of a fresh food can and store it in the refrigerator for up to three days.

Another advantage of feeding wet food is that cats like the taste of animal proteins very much. In addition, there is a very intense smell, which cats find very tasty.

Even for older cats who can no longer chew so well, wet food is very pleasant to eat due to its pulpy form.

Likewise, wet food contains few calories, as they are diluted by the water content and thus ensures less overweight in your cat.

What are the disadvantages of feeding wet food?

Wet food can only stay in the cat’s bowl for a certain amount of time. Especially in the summer on hot days, otherwise there is a risk of contamination of the food. Here, storing the leftovers in the refrigerator would help.

Also on the ökomischen side the wet food does not cut off particularly well. Especially the packaging cans are not very sustainable.

  • Vitamins A and B
  • Niacin
  • Arachidonic acid
  • Taurine

Cats cannot produce these nutrients on their own and must therefore be ingested through the food.

All this is given with a wet feeding.
