Causes of hair color change in cats

The color change in cats’ hair is somewhat more frequent than we can imagine and the possible reasons are varied. So it is necessary that, before a physical change like this, we take the animal to the veterinarian to make sure it is okay or to find the problem and the best treatment. These are the main reasons why your cat changes hair color:

  • Genetics
  • Aging
  • Stress
  • For the Sun
  • Hair problems that affect your growth cycle and weaken it
  • Vitiligo and alopecia areata
  • Lack of tyrosine
  • Next, we thoroughly discuss each possible cause of hair discoloration in cats.


The most frequent reason for this change in coloration in felines is the genetics of each one. There are breeds that when they are small have a color different from that of adults, so their cat is one of these breeds or has a mixture, maybe when they are about half a year old they start to change it.

In fact, all kittens have different hair than adult, as it is softer, provides more shelter and can be of different color, for example, being black when it is small and turning it into gray or vice versa. But at what age do cats change their hair color? Specifically, this kitten hair lasts until about 5 months and the molt to adult cat hair can last up to one year of age.

Therefore, taking into account that cats change color when they grow up, if their genetics is so marked and that it is usually about half a year of life, think if your furry fits in this cause and, if it does not present symptoms of other things or other changes, you should not worry.


The change in the color of the coat does not only make it from small to adult, but, just like people and other animals, as they get older they also change their color, as gray hair appears. This is one of the first symptoms of old age in cats. You may see that your hairy areas appear with more white or grayish hair, look well in the face and chest, two areas where they tend to grow grayer.

For example, it is common for a black cat to change color, becoming more grayish and even with whiter areas. In addition, longer and white hairs may appear, apart from the ones you already had.

Stress in cats

Anxiety and stress are factors that alter the entire organism, both in cats and in any other living being. It is common for stress to fall much more hair and hormonal changes that produce changes in the tone of the coat, always becoming a lighter hair. In addition, if the stress is very strong white areas of hair, which are gray, may appear.

If you suspect that your cat is stressed try to detect the reason and change it as soon as possible if possible, but go to the veterinarian to diagnose and give you the best treatment. Some reasons for strong stress in cats are the changes, the arrival of more animals or people at home and loud and constant noises.

For the Sun

If your cat spends a lot of time in the sun, your hair will clear up, probably in some areas more than in others. For example, normally, black cats change to a redder or brownish tone.

If we think about it carefully, it is something that also happens to people. This happens because the sun affects the structure of the hair can not only change the tone, but also dry it and make it weak, provided it is an excess of sunlight.

Problem in the hair growth cycle

Maybe the cat has a problem that slows the proper growth of the coat. The suppression of the hair cycle can produce a change in its color. In this case, the animal does not expel the hair well when the cycle ends and it remains aged, weak and of a dull color, being able to be something lighter than the usual one,

It is necessary that if you see that your cat does not change the coat well and it remains aged and turned off you take it to the vet. This will have to perform tests, such as a trichogram to check the condition of the hair and detect the problem and give you the best treatment. Some of the causes to treat can be the malnutrition that lacks any vitamin, mineral or protein, or some systemic disease that affects the whole body.

Vitiligo and alopecia

Another possibility of this change in the coat of your cat is vitiligo. It is a change in the pigmentation of the skin and hair that, in principle, does not have to suppose a health problem. However, in cats it has been linked to lupus and to uveitis, a serious inflammation in the eye. So, especially if it has been a sudden change, it is recommended to go to the veterinarian both for the diagnosis of vitiligo and for the treatment of possible symptoms if it is linked to these other diseases.

On the other hand, another problem in the hair is the alopecia areata or alopecia located in a part of the body. This is mainly detected by isolated areas where there is less fur or no longer there, but another sign is the change of color in the surrounding hair or generalized, although this last sign is less frequent.How to Know the Cat Age and

Lack of tyrosine

Tyrosine is an amino acid that intervenes in the creation of melanin, which gives color to the skin and coat. Because of this, a lack of tyrosine can cause a change in the hair color of cats. The most frequent are cases in which it goes from black to brown or reddish.

Although this problem is more common in dogs than in cats, it is necessary for a veterinary specialist to check the health of your cat, because if it is about this problem, it can lead to something more serious than a simple change of tone in the fur.
