What Vitamins Do Cats Need?

In the stage of old age, just like humans, our cats also have physiological deficiencies in nutritional substances. As a cat gets older, several changes take place in her body:

  • The metabolism slows down, becomes lazier, and gains weight;
  • The immune system weakens;
  • It increases the occurrence of bone, degenerative and dehydration diseases.

For this reason, there are a series of vitamins and supplements for elderly cats that can allow our furry friend to lead a quiet life even in the aging phase.

Vitamins for senior cats are essential as they:

  • They allow the animal to have more energy;
  • Strengthen the immune system;
  • They help regulate bone metabolism;
  • They regulate appetite, which decreases in older cats.

However, vitamins must always be specific to the individual case. So, always remember to consult your veterinarian before starting any treatment.

Important Features to consider

Cats get the vitamins they need through natural food, therefore that coming from their prey. As for specific foods, such as dry food for cats, vitamins are added synthetically because they are thermolabile. It means that they are destroyed by cooking the principal ingredient that contains them and therefore need to be reinserted artificially.

The manufacturers make a separate mention of taurine. It is an essential amino acid that the cat must take from the outside, as it cannot produce it independently. It, present in raw meat, is what we find in crunchies and for our pets, it is just like a vitamin.

To find out it contains which vitamins in normal kibble, just check the so-called nutritional additives shown on the package. In this way, you will avoid giving your cat the substances that it already gains through food separately.

Who Should Buy Cat Vitamins

We should only use the vitamins and supplements for cats when the body of the cat manifests a nutrient deficiency or of particular substances.

But how to find out what our cat needs? The first step is to visit your trusted veterinarian. It will be essential to test the symptoms that the animal shows. And subsequently, it will make a biochemical analysis of the blood to understand the values ​​of the substances in the body.

Once these steps have been carried out and its current diet analyzed, it will be possible to test more precisely if the animal is suffering from deficiency disorders and proceed with the administration of vitamins, supplements, and other substances.
