Why Use Cat Flea Shampoo?

Cat flea shampoo is easy to use, has immediate results and as a bonus the shampoo is rinsed out straight away so there is no chemical residue left behind.

Also, if the infestation is very bad it is a very quick way to get rid of most of fleas. I hesitate to say all fleas, as it can be difficult to kill them all.

If your cat reacts to the chemicals in flea collars or flea drops, shampoo would be a good alternative. Try not to get shampoo in your cat’s eyes, we don’t like shampoo in our eyes and your cat won’t either. Plus you want to make this a positive experience 🙂 so that it can be repeated when necessary.

Many flea shampoos for cats also contain a conditioner to leave your cat’s fur soft and luxurious.

What Does Cat Flea Shampoo Do?

Some cat flea shampoos will only kill adult fleas.

Although that might give the cat some immediate relief and it might be cheaper, it is better to purchase a shampoo that will kill the fleas and the flea eggs.

You do need to work the shampoo right into the fur. The temperament of your kitty may determine the effectiveness of the method. Because the cat may squirm, an odd flea or two might survive the dunking.

Does Cat Flea Shampoo Work?

Yes, it works straightaway. How long it lasts depends on which product is chosen.

cat having a shampoo

If you want ‘ínstant’ definitely use shampoo and then you can review your options. It also depends how bad the flea infestation is. If it’s really bad, you just want them gone straightaway and flea shampoo for cats will do that.

For the flea shampoo to work effectively, always start shampooing at the head, avoiding the eyes and move down the body. This is to try and prevent any fleas from jumping to the neck or head area.

Let the shampoo sit for a couple of minutes before rinsing carefully.

How Often To Use Flea Shampoo For Cats?

Mostly cat flea shampoo can be used monthly however you will need to read the product information for the flea shampoo that you purchase. Some of the more natural flea products can be used more frequently.

My Cat Hates Water

Some cats love water but we don’t usually associate cat and bath, in the same way that we associate, dog and bath. This may be something that you won’t possibly really know until you have tried giving your cat a bath. We are not talking about a long soak here, short and sweet is the key to success.

The video below gives specific instructions to make the job easy. We would suggest that it is preferably a two person job if this is an option for you.

It might not be a walk in the park bathing your cat, or you may be lucky and have a placid kitty cat that doesn’t mind some time at the beauty salon.

How To Shampoo Your Cat

  1. Use a bath, sink or container where you can comfortably shampoo the cat. If the bath is too deep for you to comfortably reach down to shampoo the cat, a laundry sink or bathroom sink will be a better option. You need to have good control of the cat.
  2. Place a non slip mat or towel on the bottom of the sink or container so your kitty is not slipping around.

    If he slips he is likely to freak out and want to run for the hills. If he is showing signs of aggression protective gloves are useful for all cat grooming, including trimming nails, bathing etc.
  3. Fill a container with warm water, not too much, several inches is fine. If you have a helper he/she can use a pitcher to gently wet the cat’s fur so that you can apply the shampoo.
  4. Use warm water to rinse the shampoo. If you have a detachable shower head that would work really well to wet the cat and rinse the shampoo. Take care around the cat’s head to ensure that no shampoo runs into the cat’s eyes. Use the shower head to direct water away from the face.
  5. Have several towels ready to dry kitty as best you can. By this time he may just be wanting to disappear but he will be flea-less, so he should be thanking you. I wouldn’t count on any thanks but you never know.

Tip: A portable grooming tub would be super handy if you have a number of pets to groom and shower or if you regularly give the cat a flea shampoo.

Is Cat Flea Shampoo Safe To Use?

Cat flea shampoo does contain chemicals. The plus is that the chemicals are washed off the skin.

It is generally recommended that cat flea shampoo not be used on kittens under twelve weeks and up to one year old. So if you have a kitten under twelve weeks old, purchase a flea shampoo that is specifically for kittens.
