If you love your cat and hate fleas as much as I do, then this article is for you. Fleas make my kitty’s life miserable and that makes me unhappy, so it has been my quest to find the best flea treatment for cats and to share it with you.

There are many good flea and tick products available these days but that’s where the confusion starts. Which product is the right choice for your cat and what is the best way to administer it? If you are as confused as I am then I don’t blame you!

This article will explain the life cycle of cat fleas, how your cat can get a flea infestation and the best ways to treat and prevent it. We will highlight the pros and cons of the best flea medicine for cats that is available today, and this will allow you to make an informed decision before you decide to make a purchase.

How did my cat get a flea infestation?

The best way to answer this question is to take a look at the life cycle of fleas in cats. Most folks believe that fleas jump from one cat to another to spread a flea infestation but this is actually a myth. Fleas jump on your cat from the environment (indoors and outdoors) and once a flea has infested your cat it will stay there for it’s entire life.

When a female flea has jumped on your cat it will start biting it’s skin almost immediately and start feeding on your kitty’s blood. This sounds gross, but fleas need to ingest blood to grow and start reproducing. It only takes 24 hours for a female flea to start laying eggs and they can lay up to 50 eggs a day.

As your cat roams through your house it drops flea eggs wherever it goes, just like a salt shaker sprinkling grains of salt around your floors, furniture and bedding where it sleeps or rests. The flea larvae hatch out within a week and in an effort to avoid light they crawl between the floorboards, and into carpets and upholstery.cute kitty

After 5 to 10 more days the larvae start spinning cocoons and quickly develop into pupae. It only takes 1 to 3 weeks for the baby fleas to emerge from the cocoons. They are sensitive to vibrations and as soon as your cat walks by they will hop on and hitch a ride. And so the flea life cycle begins again.

We also know that fleas live in your yard and garden but it’s a myth that cats who only live indoors never get fleas. These parasites are opportunistic and when we are outdoors they can jump onto our clothing and hitch a ride into our house where they hop off onto the floors and then onto our cats.

How do I know if my cat has fleas?

Looking for visible signs of a flea infestation is easier than you might think and you can follow these few easy steps:

Excessive Scratching – the first sign of trouble is when your cat gets itchy skin and starts scratching excessively. A bit of scratching now and then is normal but non-stop scratching is a sign that you should examine your furry friend for fleas. Excessive chewing, gnawing, licking and nibbling are other clues that all is not well with your kitty.

Look For Flea Dirt – if your cat has a serious flea infestation then it’s easy to see the fleas by parting their fur with your fingers or a flea comb. But often it can be more difficult and no fleas are actually visible on your cat. The clue is to look for the presence of flea dirt or flea poop on the skin of your cat.

Flea dirt contains old digested blood from the intestinal tract of the fleas and it will leave red stains on the moist paper towel as it dissolves. So your diagnosis can be easily confirmed using this simple method.

Excessive Shedding – seasonal shedding is normal for all cats but if you see signs of hair loss appearing then you should take a closer look. Patches of missing hair around the neck or tail areas are tell-tale signs of a flea infestation. This is the result of excessive scratching caused by the itching and irritation of the flea bites and the saliva of the fleas which can irritate the sensitive skin of your cat.

More Serious Signs – in extremely severe cases of flea infestation your cat will start showing signs of illness which first manifest themselves in subtle changes of behaviour. Look out for signs of loss of energy, tiredness and loss of appetite. A lacklustre cat could have a serious flea problem but allow your vet to check for other diseases as well.

How Do I Find The Best Flea Control For Cats?

It’s much easier to make informed decisions about the best cat flea treatment by first finding out what types of treatment are available and how they actually work. There are many very effective products available these days but it’s important to remember that different products work on different parts of the flea life cycle so sometimes combining two products can also be a good idea.three kittens

Some products target the adult fleas by killing them quickly and giving immediate relief while others disrupt the flea life cycle by destroying the larvae and flea eggs, so the reproductive cycle is disrupted and the entire flea population is wiped out. It’s also important to never use dog flea products on your cat as they can be poisonous and remember to always follow the product instructions closely.

Remember also that ticks on cats are rare depending on the environment your cat lives in. But sometimes it’s wise to look for the best flea and tick prevention available so you can cover all bases.

Cat Flea Allergy Dermatitis

Flea bites are irritating to your cat’s skin but there is more to it than that. Fleas also inject their own saliva into the skin when they bite and some cats can develop a serious allergic skin reaction called Flea Allergy Dermatitis. This causes serious itching and scratching with raw patches and welts developing on your kitty’s skin. Treat the fleas with a good flea remedy like Advantage which is recommended for FAD (Flea Allergy Dermatitis) and a mild cortisone skin spray.

Blood Loss (Anemia)

Fleas suck and ingest your cat’s blood. Whilst this sounds really gross it can have serious health implications. Dozens of fleas biting your cat can cause serious blood loss over time which eventually results in anemia. When this happens to small kittens they sometimes require a blood transfusion to survive. The symptoms of anemia to watch out for in your cat are lethargy, loss of energy, weight loss, boy with catpale gums and sometimes breathlessness. Treatment to eradicate the fleas is essential as well as good nutritional supplements.

Tapeworm Infestation

Fleas can carry the eggs of tapeworms in their systems and these can be transmitted to cats. Cats love to groom and lick themselves and sometimes they can swallow a flea which could be a carrier of tapeworm eggs. The tapeworm eggs hatch in the cat’s intestinal canal and the adult tapeworms then develop in your cat’s intestines. There they can deprive your cat of essential nutrients and lead to weakness and weight loss. Treatment with a good oral wormer like Milbemax, Drontal For Cats or Profender Cat Dewormer is required.

Bartonella (Cat Scratch Disease)

The organism that causes Bartonella (B. henselae) is usually passed on from one cat to another by fleas that are carriers of the disease. Most cats that are infected with Bartonella show no signs or symptoms but in severe cases some cats can show signs of illness like enlarged lymph nodes, loss of energy, fever and eye inflammation. Treatment can be complicated and should be initiated by your vet with a combination of antibiotics and can last from 4 to 6 weeks.
