Flea Infestation Signs

Just like babies, cats are very playful creatures but quite calm when not engaged in any active activity. So how do you notice that your furry has a flea infestation? Of course apart from spotting some fleas on her skin or surroundings, here are some of the red flags:

a) Never ending biting or scratching

If you notice your cat scratching herself always, the chances are, she has a flea infestation. The same habit is also true with dogs.

b) Food denial

Food denial is the initial sign you will probably notice when the fleas infest your feline. She will not feel well enough to take food down her throat.

c) Inactive

Cats are very playful pets and would hardly stay calm. Thus, when you notice that your pet does not want to play or even interact, probably she is suffering from flea plague.

d) Excess grooming (evidence of bleeding or getting sores)

Cats do love grooming themselves mostly using their tongue. However, when you notice her chewing or biting herself continuously, then probably she is dealing with fleas’ infestation. Excess grooming could bring forth sores that require immediate medical attention lest it acquires an infection. Therefore, be on the lookout.

e) Too moody

You might want to check for the presence of fleas if you notice your cat is so irritable and does not like getting bothered. Such cats will even bite you when you try to pick them or engage them in play.

Treatment types

There are several treatments of fleas in cats in the market such that choosing one can be an uphill task. However, take into consideration the needs of your feline and age as well, and you will never go wrong. Here are the various treatment types:

  • Topical treatments

Topical treatments are the most popular treatment since it is not only easy to administer on your feline but also effective in killing other pests apart from fleas. Always apply the liquid at the base of the feline’s neck to prevent it from licking the treatment. It is recommended to use one tube of the treatment per cat. Most importantly, topical treatments are packed according to the weight of the cat. Therefore, choose the treatment that suits your feline’s size. As for kittens, make sure your kitten has attained recommended age before administering the medication to her.

  • Cat Flea Shampoo

I must confess that I am very hesitant in bathing my furry feline and I am sure most of the cat parents are. However, bathing your feline comes in handy along with a preventative method after a bath, when getting rid of the fleas. There are different types of cat flea shampoos that you can choose from. Be on the lookout for the right age recommended for each shampoo and remember shampoos are not advisable for use on very young kittens.

  • Cat Flea Collars

Cat flea collars are effective flea treatment, easy to use, non-messy and a perfect supplement to flea shampoos. Collars work by emitting a constant scent that is noxious to pests alone, and your pet can wear alongside regular cat collar. If you get the top brand, it provides treatment for up to eight months upon which its effectiveness decreases. When purchasing, remember to look out for the correct size for your furry and should be specifically designed for use by the cat or the kitten

  • Cat Flea Spray and powders

While sprays and powders are not considered as flea treatments, nonetheless they are important in the holistic management of flea infestation. Powders and sprays are applied on surfaces including rugs, beddings, floor cracks, furniture, etc. to kill any hiding fleas in their different stages of lifecycles. Also, you can spray on your feline’s fur to protect her especially when outside.

  • Oral drops

Oral drops flea medications are similar to topical formulations. The only difference is the technique used in the administration of the drug. Topical applications entail application on your feline’s skin while for oral drops, you drop into her mouth. Despite being effective, some cats are not comfortable taking drugs orally.

  • Tablets

Tablet formulations are the most recent innovation in pest management specifically designed to kill adult fleas. Flea medications in tablet form contain a highly concentrated active drug that kills mature fleas in seconds. Since it is effective on adult fleas only, complement the tablet with other medications that target eggs, larvae and pupae.

What to do Before Buying Flea Treatment Medication for Cats

a) Always consult your vet

Some would argue that why spend some dollars seeking advice from your vet on flea remedy while the internet has lots of information? While the internet is a good source of information, as a responsible cat parent you would need to seek advice from your vet always. Why do I say that? Just like human beings, every cat is individualistic and what works on another cat may not work for yours.

Therefore, always have a qualified vet practitioner to evaluate the cat’s physiology and health profile so as to make an informed decision on the best flea medication for your feline.

b) Purchase from reputable sellers

Do not just go buying your pet’s medications from any seller on the market. The internet has turned the world into a small village, however, be vigilant when purchasing products online. Ensure that you order your product from the official website of the manufacturer. Alternatively, if your veterinarian has own pet supply outlet, it would be safer to purchase pet’s medications from his/her clinic.

c) Do not go cheap

Remember they say cheap is expensive. Although some of the most affordable products do exhibit the same ingredients as those perceived as expensive brands, you might never be quite certain. While it is also not bad to go for cheaper brands, do not go to the extent of compromising the quality of the product in dealing with the flea infestation.

d) Follow the manufacturer’s instructions keenly.

Reading and understanding the instructions given on the flea medication product is paramount before administering any drug. The life of your feline furry is at stake here, and you wouldn’t want to risk losing her due to mere ignorance. Also, when you do not follow instructions given, you might endanger your life and that of your family as well. Therefore, always follow directions of use to the latter.

e) Be on the lookout for possible reactions

Every medication has a potential side effect. Upon administering the drug on your feline, always be vigilant for a few hours for any possible occurrence of hypersensitivity. Also, acquaint yourself with effective ways of managing allergic reactions.

f) Know how to evaluate the drug’s effectiveness

To determine the efficacy of the drug, check the label for its promised effectiveness against your observation. For example, if the product guarantees a 90% kill of the fleas within 30 minutes or so, you should be able to observe that to verify its efficiency. Also, correct administration of the product will enhance its effectiveness.

Factors to Consider when Choosing the Best Flea Treatment for Cats​

Quick-acting and reliable

Fleas do proliferate so fast such that they do not need several months to reach their reproductive capacity. Thus, you may find yourself killing them today, but tomorrow you find other fleas already. Fleas are very resilient and prolific, and that is why you not only need to use a flea control product but also manage your environment especially where your pet resides.

Therefore, the insect’s ability to exert its action rapidly is crucial in control and management of fleas. You wouldn’t want to use a flea product that will take a whole day before seeing the result (dead fleas). Look for a flea product with a fast onset action, a rapid peak onset, and prolonged therapeutic effectiveness. For example, you will be better off with a flea product that becomes effective within 30 minutes after its administration, kills a large percentage of the fleas within six to eight hours but prolongs its effectiveness for a month or even longer.

Thus, the most important factors to look out for in a flea product is its rapid onset of action and reliability. Also, the large percentage of fleas it can kill within a short period, the better.

Controls fleas in their various life stages

Fleas are very resilient creatures that grow so fast through their developmental stages that are an egg, larva, pupae and finally mature adults. Each of the life stages presents a challenge in flea management. For instance, its eggs are so small and located in dark, moist and warm hidings. Within a few weeks, they hatch into larva that does latch on anything organic due to its strong mouth. However, due to its vulnerability to heat, they hid in floor cracks, and deep crevices and are difficult to trace. After a few weeks, they form a cocoon that protects it from the environmental hazards. Upon maturing, they break away from the cocoon, lays eggs and the start the process all over again.

Thus, targeting mature adults will partly solve the problem, look for a flea treatment product that manages each stage of the fleas’ lifecycle adequately. For holistic management of fleas, carry out a thorough treatment of your environment as well including belongings, the house, and surroundings.

Relatively safe with minimal side effects

The combination of different ingredients when manufacturing flea medications could cause clinical complaints. Some felines are hypersensitive and could suffer from gastric or skin irritation, stomach upset, etc. upon administration of the medications. Therefore, be sure to check with your veterinarian for any hypersensitivity before administering any flea treatment product.

While any medication exhibit side - effects, some of the flea medications can pose serious side effects on your feline if consumed. For instance, Fipronil component in some topical flea products can cause nausea and vomiting, abdominal upsets, and even tonic-clonic seizures. Also, Nitenpyram component leads to excessive panting and hyperexcitability of your feline within two hours of administration. Thus, follow the directions of use of these flea treatments to avoid ingestion of these components by your furry feline.

Therefore, choose a flea treatment product that does not cause any adverse effects on your cat’s health.

Ease of application or administration

Ease of administration of the treatment is essential as far as flea management is concerned. Choosing whether to administer for instance tablets or topical formulation depends on your cat. If your cat has a thick fur, it would be difficult to tell if the skin would absorb all the topical formulation. As such, you would want to administer tablets instead.
