Buying Guide How to Choose Best Flea Spray For Cat:

While you and your members of your family see a cat as one of the best companions, fleas and other parasites see pets as a nasty snack besides providing them with a warm, comfortable home. Whether your feline has been living with you for many years now or has just shown up outdoors, these bugs have their way of inviting themselves inside.

As fleas are the leading skin parasites of cats, you (as the pet owner) are the feline’s number one champion when it comes to eradicating fleas. But, how can you tell whether your cat has been attacked by fleas or not? Without making that expensive trip to the vet’s office, there are some signs to watch out for to know if your cat has these pesky parasites. It includes, but not limited to excessive grooming, shaking the head, losing fur, red bumps/scabs, restless behavior, and brown pests crawling/jumping in the cat’s fur.

If you noticed one or all of these signs, then you are concerned that your cat has fleas and will probably get into the market for preventative/repellent treatment. While safety is a big concern when it comes to treating felines for fleas, you must choose one of the best products. If you were advised by your vet to consider using flea sprays, then there are some few factors to keep in mind to help you find the right treatment.

Factors to Consider when Choosing Best Flea Spray For Cat:

Your cat’s lifestyle
As we all know, cats are one of those few pets who love exploring the world, so that at one moment, there are indoors and the next minute they are walking along the corridor or just chasing grasshoppers outdoors. It is worth noting that cats that spend much of their time outdoors are at higher risk for heavy flea infestations than those spending much time indoors. However, the later lifestyle is also susceptible. With this information at hand, you will be looking for a flea spray with strong repelling and killing abilities.

Flea species
When choosing the best cat flea spray, it is important to some knowledge of the common flea species that often attack your cat. It can indeed be an overwhelming task to know precisely the type of fleas, but the truth of the matter is that you cannot claim to be trying to wipe parasites that you do not know how they survive. You know some flea type is resistant to particular sprays. Your vet clinician can help you know the type of fleas found in your locality and may recommend the flea spray considered effective against the said species.

Cat’s age and size
Since not all cat flea sprays are created equally, there are those designed specifically for specific cat age or size. It is common sense that kittens, just like any other young pets, have more sensitive and delicate skin compared to their older counterparts. It is important, therefore, to know the age or size of your pet before choosing the best and safe flea spray solution.

Spray effectiveness
Another important factor you have to consider when choosing the best cat flea spray is its effectiveness. Are the products you are about to buy effective in both killing and repelling fleas for a longer time? The best option to respond to this concern is by looking at the active ingredients as stated in the spray’s label. Some of the most vet-recommended sprays have nearly all-natural ingredients, but it is urged that they generally take a longer time to start working and show the results you want. Others are of the school of thought that fast working flea sprays have a host of artificial ingredients. The latter option is indeed more effective, but with a few side effects.

Keeping a cat is not without a lot of responsibilities. As a loving, caring pet owner, one of the many things you will be concerned with is your feline’s well-being and health. As you may have noticed, fleas are one of these parasites that can negatively affect the health of your cat. Besides that, they can be a real nuisance when the infestation spread into your home furniture, bedding, carpets, and so on. Because of that, you must stop altogether and prevent future re-infestation.

Whether organic or chemical, all of the flea sprays making into our top ten list can afford you that great opportunity to deal with fleas once and for all! Depending on your cat’s habits, some of these sprays work extremely better than others, so we highly recommend that you take a few tries so you can find the best one for your lovely pet.
