Flea Treatment For Cats - Types Of Flea Control

Today we are swamped with a vast array of different types of flea products to use on our cats. It can be somewhat confusing for the cat owner to choose which product should be used on their cat. We will attempt to look at the different products available, what they do and their efficiency. It should be noted that no flea control method will work if you don't treat your house and garden at the same time. Only 5% of fleas actually live on your cat, the rest of the flea population is in the environment. Both your cat and home (including cat bedding etc) should be treated on the same day.

Flea collars:

There are many different types of flea collar on the market. Some are insecticide only and work by killing adult fleas on the cat. Other flea collars contain IGR's to kill the eggs and larvae.

Flea collars often only kill fleas on the cat's head and neck, but fleas further down the body survive.

Some cats can develop a rash from the chemicals in the flea collar. This is known as "flea collar dermatitis or flea collar rash".

One handy use for flea collars is to put a flea collar into your vacuum cleaner bag so that any fleas that are vacuumed up from the environment will be killed. a

Is it safe to use cat flea collar with a spot on flea treatment?

You should not use more than one flea product on your cat as both products combined may result in a toxic level of exposure to your cat, which is life threatening. ALWAYS consult with your veterinarian before using more than one flea control method on your cat.

Flea powders, shampoos, and dips:

Flea shampoos are an effective way to kill fleas on your cat. The downside is that many cats can be difficult to bathe. Also, flea shampoos  and dips will only kill the fleas on your cat at the time, and won't help prevent re-infestation. Therefore re-infestation will occur if your cat is exposed to fleas remaining in the environment or on other pets.

Shampoos and dips also need to be repeated often.

Flea combs:

Flea combFlea combs aren't overly effective, only removing 10 - 50% of fleas on your cat. If you wish to use this method place a small bowl of water with some detergent in it close by and drop the fleas into the bowl. This will drown the fleas. Placing a small amount of petroleum jelly onto the teeth of the comb will help the fleas stick to it. These can be useful when removing fleas on newborn kittens as flea products are not safe to use on very young kittens.

Oral suspensions:

Program oral suspensionProgram® and Sentinel® is given to cats via an oral suspension once a month. The product is added to the cat's food and is absorbed into the bloodstream. When a flea bites a cat treated with Program it ingests the active ingredient (lufenuron), which is passed to her eggs and prevents them from hatching. As this product only prevents eggs from hatching, an appropriate adulticide will also be needed to kill adult fleas. Seek advice from your veterinarian before using more than one product on your cat. It is also extremely important to speak to your veterinarian if you are considering treating a pregnant or nursing cat. They will be able to recommend the safest treatment for your cat.

Spot on treatments:

Topical flea controlTopical adulticide. There are several effective products on the market which are administered via liquid form to the cat's shoulders. These are available through your veterinarian or online pet product store.  These products are very effective for killing adult fleas on your cat. The active ingredient varies from product to product. Application is generally once a month.

When applying a flea product to a cat it is important to follow the instructions on the packet to the letter.   Cats are extremely sensitive to chemicals and if you are using one than one product your cat may be exposed to too many toxins, resulting in sickness or death.

Some of the most effective and popular topical flea control products used on cats (and dogs) include Advantage, Revolution and Frontline.

Revolution also kills worms (except tapeworm), so makes life a bit easier for pet owners,  Advantage cat flea control also kills flea larvae in the pet's environment too.
