If you’re allergic to cats but want one, discover how you can be allergic to some cats and not others, if cat allergies go away with exposure, and how to have a cat when you’re allergic

Being allergic to cats is quite common among humans, with many people suffering symptoms such as sneezing, itchy skin, watering eyes, coughing and wheezing whenever a cat is nearby.

Sadly this can prevent caring cat lovers from owning a cat of their own, or even worse, result in them having to give up a beloved pet to charities such as Cats Protection.

If you do own a cat when you’re allergic, it can still affect your ability to form a close bond with your pet, as you try to maintain a safe distance to keep the sneezing at bay.

However, a cat allergy doesn’t necessarily mean you can’t get a cat. There’s a lot of confusion around the exact cause of the symptoms and how to reduce their effects, but once you know the facts, there are lots of things you can try.

Busting the biggest myths about cat allergies

Are Cat allergies caused by cat hair?

Many people think that cat hair is the cause of their sneezing, but it’s actually what’s on the hair that’s the problem. Cats’ saliva contains a protein called Fel d 1, which sticks to their fur and skin when they clean themselves with their tongues. It’s this protein that most cat allergy sufferers have a reaction to, and unfortunately it’s easily spread around your home when your cat naturally sheds their fur and dead skin cells.

Can you be allergic to some cats and not others?

Different cats produce varying levels of Fel d 1, so allergy sufferers may find that they are allergic to some cats and not others. In addition, everyone’s sensitivity level to this allergen is different. If you think you’re allergic to cats but want one, try meeting some cats first, with the other members of your household too, to see if any of you have a reaction. Keep in mind that many people with an allergy to cats are also allergic to other things, such as pollen. Therefore, it might be a good idea to meet your potential new feline friend in the summer when your pollen symptoms are more pronounced, so you can best gauge how your allergies will be affected.

Which are the best cats for people with allergies?

While levels of Fel d 1 do vary, every cat produces it, so there’s no such thing as a hypoallergenic cat. Some people believe that certain breeds of cat, such as hairless Sphynx cats, are the best cats for allergies, but this isn’t the case. Hairless cats still lick themselves to stay clean causing Fel d 1 to stick to their skin, so when they shed dead skin cells called dander, the allergen can spread around the home.

Can Cat allergies go away with exposure?

Some people believe that you can build immunity to cat allergies and that the more time you spend with cats, the less severe your allergy will become, but sadly there’s no evidence to support this. This doesn’t necessarily mean you need to avoid cats altogether though, as there are some simple steps you can take to manage your allergy and still enjoy some feline companionship.

How do you treat cat allergies?

• Ask your doctor about antihistamine tablets and nasal sprays to ease your symptoms
• Groom your cat outdoors and wipe them with a damp cloth or cat-safe cleanser to remove allergens
• Avoid letting your cat lick your skin or clothes and always wash your hands after petting your cat
• Regularly wash your cat’s bedding, toys and litter tray – Fel d 1 can be found in their urine too
• Ventilate your home by opening windows for an hour each day, or use an air purifier. Avoid placing cat beds and litter trays close to air vents
• Vacuum regularly using a cleaner with a high efficiency particulate air (HEPA) filter that limits the amount of allergen released back into the air
• Avoid letting your cat into your bedroom, as allergies can become worse at night
• Try feeding your cat Purina’s new Pro Plan LiveClear cat food, designed to safely neutralise cat allergens and reduce the levels on their fur

How do antihistamines work for cat allergies?

In people with a cat allergy, when the body detects the Fel d 1 protein it produces histamine. This is normally only released when the body detects something harmful, such as an infection, but if you are allergic to cats then the usually harmless Fel d 1 protein can be mistaken for a threat.

To try to protect your body from the allergen, the histamine causes your blood vessels to expand and your skin to swell, which results in the typical allergy symptoms of itchy eyes, a running or blocked nose and sneezing.

Antihistamines are a type of medication that block the receptors in your cells that histamine binds to, preventing your symptoms before they occur or reducing their severity.

How can Purina Pro Plan LiveClear cat food help with managing cat allergens?

Purina Pro Plan LiveClear is a new cat food designed to safely neutralise the Fel d 1 allergen in your cat’s saliva, reducing the amount of active Fel d 1 they release into your home. A key ingredient in the food, a specific protein sourced from eggs, binds to the Fel d 1 in your cat’s saliva as they eat. When they groom, neutralised Fel d 1 is spread onto their skin and fur. The food has been proven to reduce the active allergen on cat hair and dander from the third week of daily feeding. It is completely safe for your cat as the key ingredient is simply digested by them like any other protein. The food also offers great-tasting nutrition.
