How Long Does It Take For Cat Hair To Regrow?

There are several reasons why a cat may need to regrow its fur. Sometimes it's a tiny area following a visit to the veterinarian, and other times it's the entire body due to matting.

In either case, you may wonder how long it will be before they don their magnificent coats again.

In general, it takes between 4 and 6 months for a longhaired cat's fur to regrow and between 2 and 3 months for a shorthaired cat's fur to regrow.

In "How Long Does It Take For Cat Hair to Regrow?" by BestForPets (bestforpets.org), we discuss a few techniques that can help the fur regrow more quickly, as well as factors that may prevent the hair from growing back at all.


Why Would Anyone Need to Shave a Cat?

There are several instances in which it may be essential to shave or trim a cat’s coat.

1. Mats

Longhaired cats are most susceptible to this condition, although it may affect practically any cat if they are not groomed frequently. This is a regular occurrence among cats rescued from situations of neglect.

Although while cats normally do an outstanding job of grooming themselves, they still require assistance, especially if they have medium or long fur.

This is also a greater concern for cats who are overweight, elderly, or have a physical condition that makes it harder for them to reach particular regions. If mats begin to take over, brushing will only do harm to the cat; shaving is preferable.

2. Surgery

As part of preparing a cat for surgery, the region that will be operated on is shaved to maintain cleanliness. Also, it helps keep the sutures clean and allows you to monitor for infection.

3. Grooming Purposes

Some individuals delight in giving their cats humorous haircuts, such as the notorious lion cut.

Nevertheless, this should only be done by a professional groomer if your cat has to be shaved down due to mats or if your longhaired cat dislikes being handled and shaving them sometimes prevents mats from growing.

Have in mind that many cats experience anxiety when they are shaved, and this should only be done if there are no other alternatives.

4. Medical Condition

Some health issues might result in hair loss or make it difficult for hair to regrow. Therefore, these conditions will require veterinary care.

  • Ringworm: This is one of the most common reasons of hair loss in cats. This is not a parasite, but rather a very infectious fungal illness among cats. Cats lose their hair in red, circular spots, and their skin is flaky.
  • Fleas, ticks, and mites: These parasites can drive cats to scratch themselves so much that they develop bald areas.
  • Allergies: This is the most prevalent cause of hair loss. If a cat has an allergic reaction to something in the environment or to food, they may lick and scratch themselves to the point where they develop bald patches.

In each of these instances, you must have your veterinarian treat your cat.

Can You Shave Your Cat?

That is not advised. It has been known for well-meaning cat owners to accidently nick their cat’s skin when attempting to cut a mat. The skin of a cat is elastic and delicate. When you pull up on the fur, the skin will move along with it, increasing the risk of a cut.

If you wish to remove a mat, you should see your veterinarian or a groomer. Use a comb to create a barrier between the mat and your cat’s skin if necessary.

Cats may not often enjoy being groomed and may move too much for their safety, therefore it is best to leave this task to the experts.

How Long Will It Take for Cat Hair to Grow Back?

There are a number of variables that can affect how quickly a cat’s fur grows back. The length of your cat’s hair and whether it was shaved for a cause or fell out due to a health problem can make a difference. Also, the longer it may take for your cat’s fur to regrow, the older they are.

Within a few weeks, the cat’s fur will begin to regrow on a healthy cat that has been shaved. Cats with short fur normally regrow their hair in around two months. It depends on the thickness and length of the fur, but it might take up to six months for longhaired cats to regrow their coats.

Are There Ways to Encourage Faster Hair Growth?

The health of your cat is one of the primary determinants of how quickly their fur grows. Diet plays a vital role in a cat’s overall health.

Ensure that your cat’s diet is enriched with omega-3 fatty acids, especially those derived from fish oil, since they are beneficial to the health of the hair and skin. Also, consider zinc and vitamins A and E.

In addition, animal protein-rich diets can support your cat’s energy and hair growth. In fact, if your cat’s hair does not appear to be growing quickly enough, it may be due to a lack of high-quality protein in its diet.

If your cat’s hair is growing back slowly, it may be because he or she continues to overgroom the region. Try using an electronic collar or a recovery suit to prevent your cat from licking and biting the affected region.

Lastly, if you know that particular items stress out your cat, attempt to eliminate them or see your veterinarian about anxiety-reduction techniques. You may also try calming products for cats.


In the conclusion of “How Long Does It Take For Cat Hair to Regrow?” by BestForPets (bestforpets.org), several causes can result in a cat having a shaved patch or hair loss, and other variables can affect how long it takes for the hair to regrow.

Ensure your cat gets a nutritious food and adequate vitamins, minerals, and other supplements to promote healthy skin and fur.

Overall, be patient and keep your cat healthy and happy, and before you realize it, your cat’s luxuriant fur will have grown back.
