Hypoallergenic Cat Food: Can Humans Eat It Too?

Cat allergies are a common problem, with around one in five adults suffering from some level of sensitivity to cat allergens. To address this issue, Purina has developed a new type of cat food called Pro Plan LiveClear, which aims to reduce the major allergen, Fel D1, in cat hair and dander. This allergen is a type of protein found in feline saliva, which is spread to the fur during grooming and can cause allergic reactions in humans. LiveClear contains an egg-based ingredient with Fel D1 antibodies, which neutralises the allergen in the cat's saliva, reducing its presence in the environment. While some people have found this product effective, others have reported mixed results, with no significant differences in allergy symptoms when compared to a control group. The food is available in several formulas, including chicken and rice, salmon and rice, and turkey and oatmeal, and is designed for adult cats.

The science behind Purina LiveClear

Purina Pro Plan LiveClear is a revolutionary cat food that reduces the major allergen in cat hair and dander, Fel D1, by an average of 47% starting in the third week of daily feeding. This is achieved through over a decade of research, which discovered that feeding cats a key protein sourced from eggs binds to and neutralises the Fel D1 allergen in their saliva. This, in turn, reduces the amount of Fel D1 that is transferred to their hair and dander when they groom themselves.

The LiveClear line includes seven different recipes – one for kittens, five for adult cats, and one for senior cats – as well as an allergen-reducing rinse-free shampoo. The recipes include protein from dried egg, as well as either fresh chicken or chicken meal, turkey, or salmon as the main source of protein. The line is well-liked by customers, with reviews stating that the product yields a noticeable reduction in allergy symptoms.

While Purina's research has not been published in any peer-reviewed journals, the product has received the Good Housekeeping Seal, and the positive customer reviews seem to support the efficacy of LiveClear cat foods for reducing cat allergens.

How Purina LiveClear works

Purina LiveClear is a revolutionary cat food designed to reduce the major allergen in cat hair and dander, Fel D 1, by an average of 47% starting in the third week of daily feeding. All cats produce this common allergen in their saliva, and when they groom themselves, they spread it onto their hair and dander, which can cause allergic reactions in humans.

Purina LiveClear works by using a key protein sourced from eggs that binds to the Fel D 1 allergen in cat saliva and neutralises it. This is achieved by exposing chickens to cat allergens and collecting their eggs, which contain high levels of anti-Fel D 1 antibody. The egg proteins are then sprayed onto cat biscuits, so that cats end up consuming antibodies to their own allergen. When they groom themselves, the Fel D 1 is taken out and inactivated.

It is important to note that LiveClear should be fed to cats daily for optimal benefit. While it should be the primary diet, providing occasional wet cat food or treats is acceptable. LiveClear is also available in formulas for kittens, adult cats, and senior cats, as well as those with sensitive skin and stomachs, indoor cats, and weight management.

Effectiveness of Purina LiveClear

Purina ProPlan LiveClear is a line of dry cat food products that claims to reduce allergens in cat hair and dander. The product line includes seven recipes – one for kittens, five for adult cats, and one for senior cats. The line also includes an allergen-reducing rinse-free shampoo.

The effectiveness of Purina LiveClear in reducing cat allergens seems to be a mixed bag. While Purina's research claims that cats who eat LiveClear have a 47% reduction in allergens on their coat, independent reviews are more varied. Some customers have reported a noticeable reduction in allergy symptoms, while others have seen little to no change.

The active ingredient in LiveClear is a specific protein found in eggs that binds to and neutralizes Fel D1, a common allergen in cat saliva. This protein is produced by exposing chickens to cat allergens and collecting their eggs, which then contain high levels of anti-Fel D1 antibody.

While the product seems to work for some people, it's important to note that it may not be effective for everyone. The only research supporting the product's efficacy was funded and conducted by Purina, and they have not published their results in any peer-reviewed journals. Additionally, independent reviews have noted that the food contains questionable ingredients, such as corn, wheat, and soy, which may not be ideal for cats.

Overall, Purina LiveClear may be worth trying for pet owners who suffer from allergies, but it may not work for all cats, and the long-term effects of the product are still unknown.

Pros and cons of Purina LiveClear

Purina LiveClear is a revolutionary cat food that claims to reduce the major allergen in cat hair and dander, Fel D1, by an average of 47% starting in the third week of daily feeding. Here are some pros and cons of Purina LiveClear:

Pros:

• Reduces allergens: Purina LiveClear is the first cat food shown to reduce the major allergen, Fel D1, in cat hair and dander. This can help people with cat allergies manage their symptoms and enjoy the company of cats without suffering from allergic reactions.
• Safe and effective: LiveClear is backed by more than a decade of research and is shown to safely and effectively reduce allergens in cat hair and dander. It does not affect the cat's overall physiology and is as safe as any other cat food.
• Variety of formulas: LiveClear offers a variety of formulas for different life stages and nutritional needs, including kittens, adults, seniors, indoor cats, weight management, and sensitive skin and stomach.
• Positive customer reviews: LiveClear has received mostly positive reviews from customers, with many reporting a noticeable reduction in allergy symptoms. The small kibble size also makes it appropriate for cats of all ages.
• High protein and fortified with probiotics: LiveClear formulas contain high-quality sources of animal protein and are fortified with live probiotics for digestive and immune health.

Cons:

• Questionable ingredient quality: Some LiveClear formulas contain lower-quality fillers like corn, wheat, and soy, as well as vaguely-named animal by-products that could trigger allergies or sensitivities in some cats.
• Limited variety: LiveClear currently only offers dry food formulas and does not have any wet food or grain-free options. This may be a problem for cats with grain or gluten allergies or for picky eaters.
• Expensive: LiveClear is more expensive than other Purina products, ranging from $0.29 to $0.46 per ounce. This may be a significant expense for cat owners, especially those with multiple cats.
• Mixed results: While many customers have reported a reduction in allergy symptoms, there are also some reviews stating that LiveClear did not work for them. Individual results may vary, and it may not be effective for everyone.
• Digestive issues: Some cats may experience digestive issues when first switching to LiveClear products. It is recommended to introduce the food gradually to help with the transition.

Other ways to reduce cat allergens

There are several ways to reduce cat allergens in your home. Here are some tips to help minimise the risk:

Reduce Exposure to Cats

If you are allergic to cats, it is advisable to reduce direct contact with them. This includes wearing a mask with an N95 respirator when around cats and washing your hands with soap and water after touching them. Even if you don't have a cat yourself, it's important to be cautious of visitors who do as they can bring cat dander into your home on their clothing and luggage.

Plan Ahead

If you or someone in your household is allergic, but you still want to keep a cat, there are some precautions you can take. Before the cat arrives, ask that it be kept out of the rooms where the allergic person will sleep for a few weeks. Starting allergy medication a few weeks in advance can also help prevent an allergic reaction from occurring.

Use HEPA Air Filters

Using a central air cleaner and HEPA filters on vents can help capture cat dander and prevent it from circulating throughout the house.

Bathe and Brush Your Cat Regularly

The effectiveness of bathing your cat to reduce allergens is uncertain, but if your cat tolerates it, it may be worth trying to see if it lessens allergy symptoms.

Reduce Exposure to Cat Dander

Limit your exposure to the cat by assigning care responsibilities, such as cleaning the litter box, to other family members. Restrict the cat's access to certain sections of the house, particularly the bedroom of the allergic person. Regular and rigorous cleaning is essential to minimise dander—sweep, mop, vacuum, and dust furniture often. Use a vacuum with a HEPA filter, and consider removing carpets and drapes that can trap dander.
