Adams Plus Flea & Tick Shampoo with Precor is formulated for cats, kittens, dogs, and puppies over 12 weeks of age, making it suitable for a wide range of pets. One of its main strengths is the ability to kill adult fleas, flea eggs, ticks, and lice, providing comprehensive pest control. The presence of Precor, an Insect Growth Regulator, helps prevent flea reinfestation by inhibiting the hatching of flea eggs for up to 28 days.

This shampoo is also designed for pets with sensitive skin, incorporating soothing ingredients like aloe vera, lanolin, coconut extract, and oatmeal, which can be beneficial for maintaining your pet's skin health. Additionally, it conditions the coat, leaving it soft and shiny with a pleasant, light fragrance. However, it requires careful application and rinsing, and can't be used on pets younger than 12 weeks.

While it is effective, users need to repeat the application every 7 to 10 days for adult flea relief, which might be cumbersome for some. The relatively small amount needed per use makes it economical, but the frequency of use could offset this. It is a reliable option for those seeking thorough flea and tick control while also catering to sensitive skin needs.

Buying Guide for the Best Flea Shampoos

Choosing the right flea shampoo for your pet is crucial to ensure their comfort and health. Flea shampoos are designed to eliminate fleas and other parasites from your pet's fur and skin. When selecting a flea shampoo, it's important to consider several key specifications to ensure you pick the best one for your pet's needs. Understanding these specifications will help you make an informed decision and keep your pet happy and healthy.
Active IngredientsActive ingredients in flea shampoos are the chemicals that kill fleas and other parasites. Common active ingredients include pyrethrins, permethrin, and natural oils like neem or eucalyptus. It's important because the effectiveness of the shampoo depends on these ingredients. If your pet has sensitive skin or allergies, you might want to opt for a shampoo with natural ingredients. For severe infestations, stronger chemicals might be necessary. Always check with your vet if you're unsure which active ingredient is best for your pet.
Pet TypeFlea shampoos are often formulated specifically for dogs or cats, and using the wrong type can be harmful. This specification is crucial because some ingredients safe for dogs can be toxic to cats. Always ensure the shampoo is labeled for the type of pet you have. If you have both dogs and cats, look for a product that is safe for both, but always double-check the label and consult your vet if needed.
Age SuitabilityAge suitability refers to whether the flea shampoo is safe for use on puppies, kittens, adult pets, or senior pets. This is important because young and old pets have more sensitive skin and immune systems. Shampoos for puppies and kittens are usually milder and free from harsh chemicals. For adult pets, you can use standard flea shampoos, while senior pets might need a gentler formula. Always check the age recommendation on the product label.
Skin SensitivitySkin sensitivity is a measure of how gentle the shampoo is on your pet's skin. Pets with sensitive skin or allergies need a hypoallergenic or gentle formula to avoid irritation. This is important to prevent further skin issues. Look for shampoos labeled as hypoallergenic or formulated for sensitive skin. If your pet has a history of skin problems, consult your vet for recommendations.
FragranceFragrance in flea shampoos can make your pet smell pleasant after a bath, but it's important to choose a scent that won't irritate your pet's skin or nose. Some pets are sensitive to strong fragrances, which can cause discomfort or allergic reactions. If your pet is sensitive to smells, opt for a fragrance-free or lightly scented shampoo. Always observe your pet's reaction to a new shampoo and discontinue use if any irritation occurs.
Additional BenefitsSome flea shampoos offer additional benefits such as moisturizing, conditioning, or detangling properties. These can be important if your pet has dry skin, a long coat, or tends to get tangles. Moisturizing shampoos help keep the skin hydrated, while conditioning shampoos can make the fur softer and easier to manage. Consider your pet's specific needs when choosing a shampoo with additional benefits.
