Cats and Their Fleas

Cats can suffer from many types of parasites but the most common parasite found on a cat’s kin is the cat flea (Ctenocephalides felis). Outdoor cats and indoor cats can be affected by this very persistent parasite.

A cat becomes infected when a flee jumps onto its fur, and starts feeding on its blood. Some cats are hypersensitive to fleas and flea bites can really trouble but most cats only experience a mild itch. Older cats, and sick cats, can become very ill as fleas can cause anemia.

What Do Cat Fleas Look Like?

Most of the time you cannot see the fleas on your cat but you can normally spot their faeces. They look like small black and white grains, and are made up out of dried blood.

The fleas are small, dark and brown about 2.5 millimeters, and they can normally found along your cat’s back and hind quarters. Look around the base of your cat’s tail, and you will normally find them if you suspect your cats has fleas.

Flea Treatments

There are many different ways in which to treat fleas. New products such as Advantage and Frontline have more or less replaced powders, sprays and shampoos. The new products claim to be a much safer way to deal with and treat the problem of cat fleas but I am still a bit reluctant to use insecticides.

By using insecticides you also run the risk of causing an allergic reaction. Allergic reaction from Advantage and Frontline can cause skin problems, and trigger anaphylactic shock. This happened to one of my cats and it was a frightening experience.

How to Prevent Cat Fleas

There are some really simple ways in which to prevent cat fleas, and here are some easy follow tips.

  • Supplement your cat’s diet with Brewers Yeast.
  • Try one of the many other preventative cat flea treatments on the market
  • Make sure you keep the cat’s sleeping area and favorite spots are kept clean
  • Hoover your home, and consider investing in a steam cleaner
  • Brush your cat’s coat

Health Benefits of Brewer's yeast

Brewer’s yeast is really good for cats, and can benefit their coat, eyes and improve oral health. It is almost a complete food as it contains proteins, B vitamins, chromium, zinc, iron, a wide range of amino acids and many trace elements. It can also help to control fleas as the yeast is toxic to fleas.

Flea Control

Cats can suffer allergic reactions to flea bites, and bites can even lead to blood problems.

Brewer’s yeast is a perfect, natural way to control fleas and unless your cat is allergic to Brewer’s yeast it is non-toxic. It works by a chemical reaction which takes place inside your cat’s body, and produces a smell which repels fleas. Brewer’s can even in its powder form repel fleas by applying it to your cat’s coat.

How to Check Your Cat for Fleas

Brewer's yeast and Other Health Benefits

Brewer’s yeast is not only a good way of preventing fleas but it also has other health benefits. Whilst the yeast in contained in Brewer’s yeast is toxic to fleas, it will not cause any harm to your cat.

Many cat owners see an improvement in their cat’s coat, eyes and Brewer’s yeast can also help to improve oral health. Brewer’s yeast is more or less a complete food. It contains B Vitamins, proteins, chromium, zinc, iron, amino acids and also many trace elements.

Flea Control and Brewer’s Yeast

Many cats suffer allergic reactions to flea bites, and in the long term bites can even lead to blood problems in cats. Many cat owners are surprised that Brewer’s yeast work but it has been recommended by veterinarians and breeders for a long time. It works by a chemical reaction which takes place inside the cat’s body, and it is thought it produces a smell which can repel fleas.

Different forms Of Brewer’s Yeast

The simplest way to administer Brewer’s yeast to your cat is in tablet format. Most of the cats I know will just eat the tablets with their normal biscuits. As a matter of fact, they seem to be quite keen on them.

You can also by flaked or powdered Brewer’s yeast. The flakes can be blended into wet food, and so can the powder.

If your cat already has fleas, you can even apply the powder to your cat’s coat to kill off any fleas. I have tried this with friends’ cats and it works a treat. The other advantage of using Brewer’s yeast as a powder is that you know as an owner, your cat is not going to be ingesting anything harmful.

Vitamin B and Better Cat Health

The B vitamins in Brewer’s yeast can help to protect your cat’s health in more ways than one. B vitamins are vital for human health but they are equally important to our cats’ health. Cats, just like us humans, rely on B vitamins to be able to transform fats, proteins and carbohydrates into energy.

Vitamin B will also help to support your cat’s nervous system and keep his liver in good shape. There is even a lot of evidence which seems to suggest that the chromium in Brewer’s yeast can support cats with diabetes, and help to prevent infections.

How much Brewer’s yeast should you give your cat?

There are no hard and fast rules but 1 mg for every two kilos of your pet’s body weight. My cats like the flakes and they get about 1 tablespoon per day mixed with their biscuits.

Other Feline Diseases

There are many feline illnesses which might be a problem for your cat.

Most cat owners do vaccinate their cats so they are unlikely to encounter the majority of them but it is still a good idea to be aware of health problems.

Spend some time with your cat every day to ensure he or she is healthy. Brushing and stroking their coats allows for time to inspect them for lumps and bumps. A problem picked up early is more likely to be successfully put right.

Outside cats also tend to fight and dispute their territory. This can lead to some nasty injuries which can lead to abscesses. Having an abscess seen to is the most common reason for emergency visits to veterinarian. Cat bites can not only be very infectious but they are often deep, and sometimes a cat can end up with multiple bites during a fight.

      Fleas have been awful this year. I was not aware of this method. I will have to give it a try.

      If your cats do not have fleas you should not bathe them. I would not go to Walmart if your cats or kittens have fleas, I would always suggest you visit a qualified veterinarian. Brewers Yeast does work and is safe to add to food but it is not instant. A lot of flea treatments work within 24 hours, ask your vet for the best advice.

      I've got 3 RagDoll Cat/kittens who haven't known infestation, until we recently moved In with a friend.

      the kittens are a out 10 weeks old, and I've already bathed the lot of them using lukewarm water, and must a quarter sized dab of suave shampoo/conditioner.

      the Queen did well, as I used to bathe her semi regularly as a kitten. She's NEVER had fleas or worms I n her life! And, we are All of us, just beside ourselves with what's occurred!

      I googled it to find this information, so have taken precautions to insure their safety, but plan to head to WalMart or petsmart to pick up some pesticide prevention to accompany their baths. Question, can cats/kittens ever become sickly and die from bathing them to combat fleas?

      Not having carpets really helps when it comes to flea control. I am not a lover of carpets and I really do think they can be the home of so many nasty things.

      So far, this year, I've been able to control the flea problem by surrounding my mobile home (and underneath) with a boric acid roach powder that also kills fleas. Inside, I use it around the base of the cabinets and outside edges that the cats don't have access to, Then, I placed cedar chips inside and under their cushions that they lay on because fleas don't like cedar. I also have a combination spray of lemon juice and clorox that I use on hard surfaces where they sometimes lay.

      Besides all of that, brushing them almost every day seems to help the most. And then I use a flea comb just to be sure. Occasionally, I pick 1 or 2 off, but that's controlling them when you live in Southeast Texas, believe me!

      One other thing I do since we don't have carpet (which is probably a good thing), I try to sweep every day to get up the little tufts of hair the cats leave in the corners and edges because fleas like to hang out in the hair. That prevents a lot of problems also.

      If it gets to the point where none of this is working, I'll try the yeast, though. It's a good suggestion and I thank you for sharing it!

      Good information for cat owners; didn't mind learning the facts myself though I don't have a cat at the moment. Thanks for this very useful article.
