My review

We all could use some guidance when purchasing cat flea medicine, especially if it is the first purchase. Therefore, this article gives an in-depth analysis of the treatment methodologies of cats attacked by fleas, including the best flea medicine for cats.

Additionally, I have included an elaborate buyers’ guide that will give you an insight into the features to pay attention to when purchasing treatment products. Also, I have provided answers to some questions that are often asked by buyers.

What Are Most Effective Cat Flea Treatment Types

Knowing the types of treatments available will make the decision-making process swift and easy. Being conversant with the types of medication would also help you detect when the treatment is not working since you’ll know what to expect.

Pills

Flea controlling pills are cat flea meds that have recently arrived on the pesticide market. They function by entering the cat’s blood, after which they make the blood poisonous enough to kill the adult flea instantly after sucking the contaminated blood. The pills, however, do not affect the larvae or the eggs. Therefore, it is possible to use oral flea medicine for cats with other flea control products that deal with all growth stages.

Drops

Drops are applied to the cat’s skin. They are designed to kill and repel fleas. They kill the bugs through contact, and hence the pet would not have to be bitten by fleas. Like other treatment products, drops are made distinctly according to the pet’s age and weight, and therefore, you should always choose the appropriate one for your cat. A disadvantage of drops is that they can be toxic when ingested. Thus, other pets and kids should stay away from the cat until the product dries.

Topical Solutions

These solutions are absorbed into the blood via the animal’s skin. Topical products terminate the pest’s life once they suck the blood that is highly concentrated with the pesticide. Besides, other topical solutions emit toxic fumes which cause suffocation only to the pests. These products get rid of the eggs too, and should be applied monthly. Additionally, purchasing topical solution medications is easy since there is no prescription required.

Flea Collars

Flea collars can easily supplement shampoos. Collars consistently produce fumes that run through the cat’s body to suffocate the parasites. The fumes produced are only toxic to the pest and not the pet. The eradication of the pests will be a success if these collars are used together with other medications to complement each other.

Sprays

Sprays are versatile since they do not only limit their function to the animals, but they can also be used to spray the infested pet and where it sleeps and the environment around. Additionally, they are great for preventing infestation.

Natural Remedies

Natural remedies are known for their lack of side effects. It is possibly the reason why people opt for them since they are a safer option. The natural flea killer for cats methods involves using boiled rosemary leaves to act as a flea repellant.

Also, juice extracted from aloe vera does a great job of repelling fleas due to the strong smell. Some people also use salt to dehydrate the pests and eggs, thus killing them. People make discoveries on home remedies daily to control pests that may attack their pets. Nonetheless, commercial medications will always be more effective since the home remedies are mostly trial and error.

Main Composition of the Cat Flea Products

One thing that stands out as a common factor that distinguishes cat flea products is the composition or balancing of chemicals in the pesticide. Most people ask themselves, “how does cat flea medicine work?” Knowing the ingredients of these products and their specific functions will help you understand how the medications work.

The common ingredients include Fipronil and s-methoprene. The two are mostly combined since they perform different functions in pest eradication. Fipronil terminates the pests’ life, and the S-methoprene inhibits growth.

Another frequently used combination is permethrin, together with imidacloprid. Whereby, the permethrin kills the parasites by shuttering the nervous system, while imidacloprid paralyzes and gets rid of pests.

It can be confusing when looking for an appropriate pesticide in the pet store, especially if you are new to purchasing these products. Most of them look almost the same, and it is where the confusion arises. Arm yourself with detailed information and features of your preferred product to beat this confusion.

I have put together a few factors to consider when purchasing the treatment products. The goal of this guide is to assist you in getting the appropriate cat flea treatment that will be ideal for the situation at hand or level of infestation. I also included in this guide other alternative methods that can be effective in the eradication and prevention of these parasites.

Fast-Acting and Effectiveness of the Product

Fleas multiply rapidly, and if quick measures are not taken to eliminate them, it will be overwhelming and impossible to control them. You should, therefore, be careful enough to ensure you select a medication that works fast.

Aside from multiplying faster, fleas are resilient. Even after killing some, their counterparts will still jump on the host animal. Also, the pet will still be at risk of attack by the same parasites if their beddings and where they sleep are not equally treated. Thus, you should opt for the treatment that can keep up with the pace at which these parasites multiply.

The fast-acting feature is what should be considered first since it isn’t a good idea purchasing medicine that will take time to treat the pet, especially if it is suffering. Slow acting treatments only prolong the suffering of the pet. The faster this procedure is done, the better since fleas can transmit diseases and worms such as tapeworms to the host.

Different brands have different time limits within which the medication takes action. Some of them take charge within 30 minutes, while in others, the effect is seen within 24 hours. All these indications mean that within the stipulated period, 99% of the pests will be killed. On top of the rapid action, ensure that the product you purchase can last longer. The importance of this is that it will offer flea prevention for cats for an extended period.

Capability to Work on All Flea Growth Stages

As mentioned earlier, fleas are prolific organisms. Immediately the adult begins to suck blood, the eggs it lays add up to 50 in one day. Therefore, they need to be curbed at an early stage before they start biting. Killing adults is one way of arresting their multiplication before they become a menace since it will be impossible for the eggs to be laid.

Controlling fleas is done best by getting rid of the larvae together with the eggs before they mature to adults. These are the most delicate stages in the growth cycle, and therefore, if a good medication is used to eradicate them at these stages, the process will be successful.

The larvae are sensitive to heat or sunlight, and thus they hide in carpets and other completely hidden places, including the pet’s skin and cracks on the floor. Similarly, the eggs also have the same level of sensitivity, and they hide in the exact places. Hence, purchasing an effective medication that deals with all these growth stages ensures the prevention of an attack by these pests or a reoccurring infestation.

Finding the best flea killer for cats that can act on all the growth stages is the only way to relieve the pet from its misery. All in all, to achieve 99% eradication, you need to tighten the measure.

Side Effects

Nearly all insecticides have side effects. Therefore, it is wrong to say that a pesticide is completely harmless. The product you consider buying should be safe for the cat and other pets as well as people at home.

Different products have different components that might react negatively with the cat’s body; for example, oral pills can cause stomach irritations, or the sprays can cause itching. The pet might also experience allergic reactions.

Hence it’s a wakeup call as a pet owner to know your pets well. In case of any challenges, you should consult a vet for further clarification on what product to buy.

Remember, the main goal is to save your little friend from the torment of these parasites. Hence, choosing a pesticide that has extremely adverse effects will add more troubles to the cat. The treatments will always have side effects. What you need to do is be wise when selecting and put the needs of the pet first.

Ease of Usage

Treatment administration should be less complicated right from the instructions. If you notice that the instructions are complex, then that is evidence that it will be more complicated to use it correctly. If understanding the instructions proves to be difficult, chances are the administration of the medicine will be done wrongly.

Capability to Eliminate Other Pests

Some flea treatment products also protect against other pests such as ticks, chewing lice, and mosquitoes. If you are in a region where these pests are present, then it would be better to purchase a treatment that will eliminate them all.

Sometimes, the manufacturer’s information about the usage of a product might not address everything you would like to know. Below I have compiled questions asked by most people when they want to use flea treatment products.
