Why is my cat shedding so much? 3 surprising things that could be causing it

When you share your life with cats, you expect to deal with some shedding. There’s always bound to be a bit of cat hair on your furniture and clothes, and this is especially true when your cat is actively shedding. Brushing your feline is a great way to eliminate dirt, dander, and dead hair from his coat. It also increases blood circulation and improves the skin’s general condition. But if you notice your pet losing significantly more hair than usual, you should look for a deeper issue that could be causing the excess shedding.

Why is my cat shedding so much?

Allergies

If your cat sheds a lot, allergies could be to blame. The key to fixing this issue will be determining what kitty is allergic to. Cats who shed excessively during certain times of the year, like the spring and fall, may be allergic to plants and trees that are in bloom at the time. Just like humans experience fluctuating allergies, so can your little guy. This can sometimes be difficult to spot, though, since he will naturally shed at these times of the year.

Food allergies can be common in animals too. And lastly, it’s possible that your cat is allergic to something else in the environment, such as dust, perfume, and even cleaning products. If your cat has an allergy, you might notice that he’s increasingly itchy, shedding a lot, and losing so much hair that he’s developing bald spots. Your vet can help identify the cause of the allergy and provide a solution to make your mouser feel more comfortable.

Stress

Stress can cause cats to both over-groom and not groom enough, which can contribute to increased shedding.

If your furry friend is stressed, you might notice other symptoms as well. Your cat might lose his appetite, start sleeping more or less, and become antisocial, retreating to secluded areas in your home. In some cases, a stressed cat might react aggressively to other family members with whom he’s usually friendly and comfortable.

If you notice some of these signs, then stress might be behind your pal’s increased hair loss. You’ll need to try to identify the stressor. Think about any lifestyle changes that you’ve made recently, like bringing home a new baby, adopting a new pet, or moving to a new house. Any shifts like these can be a major source of stress for cats. You can help reduce your cat’s stress by giving him a spot in your home where he feels safe and comfortable. This might mean a room all to himself. You can also try using cat pheromones to help calm and reassure your cat.

Pregnancy

Even pregnancy might increase hair loss. The hormone changes can cause your female cat to lose more hair while she’s pregnant. The good news is that this is temporary, and once your cat gives birth and her body goes back to normal, the excess shedding should resolve.

Why a vet check is important

Several other health conditions can cause excessive shedding in cats. Ringworm, thyroid disease, fleas, and other issues can make your cat lose more hair than normal. Sometimes a pet can have a reaction to a medication or a flea treatment that causes hair loss. If you notice any changes in your cat’s health, including increased shedding, it’s always a good idea to take your cat to the vet for a checkup, just in case.

Most of the time, increased shedding is harmless, and once you determine what’s causing it, you may be able to reduce it. Even factors like diet and nutrition can contribute, so it’s important to carefully consider all the factors. In the meantime, be sure you have the right tools to help control the hair in your home. A powerful vacuum designed for homes with pets can help, and a few lint rollers are essential. Regularly cleaning up cat hair can help reduce how much of it ends up on your clothes.

Few first-time cat owners expect their cats to be affectionate, yet many cats seek their owner's attention. Compared to dogs, cats are typically thought of as more standoffish and less loving. That's certainly not always the case. You may be surprised when your otherwise aloof cat prefers to sleep in your bed over any other place in the house, but cats have many reasons for wanting to sleep in your bed. Read on to learn why your cat likes sleeping in your bed and the pros and cons of letting them do so.

Reasons your cat likes sleeping on your bed
How did your bed become your kitty's favorite sleep space? Several reasons could be in play.
Your cat loves you
Though they sometimes act indifferent, cats love people just as much as dogs do. Sleeping in your bed may be your cat's way of letting you know they care. When your cat sleeps with you, they show that they enjoy your company. This is especially common if you met your cat during the first four to nine weeks of their life when imprinting occurs. If you were a stable and caring presence during this time, you've likely imprinted on your cat and gained their complete adoration and trust.
Your bed is oh-so-comfortable
Cats can sleep up to 15 hours a day -- they are sleep pros. They’ve probably tried to nap in every spot in your home, so they know the comfiest, warmest, and best locations for napping. It makes sense that they would try sleeping in your bed. And all the blankets and pillows you put on your bed for yourself only make it more enticing for your cat. After all, you find your bed comfy, so why wouldn’t they?

Will neutering your cat prevent destructive behavior? Here's what you need to know

If you've adopted a male cat from a shelter or rescue, chances are your cat is already neutered. But if you've gotten your cat from a private breeder or seller, then you might be struggling with the decision to neuter your cat. When making that decision, it's important to think carefully about the pros and cons of that procedure. Neutering can have a strong effect on your male cat's behavior, so make sure you know what to expect from un-neutered male cat behavior when deciding on the best option for you and your cat.

What happens if I don't neuter my cat?
According to VCA Hospitals, un-neutered cats might contribute to the cat population control issue. Millions of cats are euthanized each year because there aren't enough homes for them, and an un-neutered male cat who comes into contact with an unspayed female can contribute to this ongoing issue.
Un-neutered male cat behavior can include several undesirable habits. Many un-neutered cats spray urine as a way of marking their territory, and they might do this within and outside of your home. An un-neutered cat is also more likely to be aggressive toward another un-neutered male. This is caused by competition between males who are trying to protect their territory, and these fights can result in serious injuries.
Cats that have not been fixed are also more likely to roam and travel great distances, particularly during mating season. This sexual interest may drive your cat to leave home and can increase the chances of his getting lost or injured while traveling.
