SIX reasons Why Your Cat Hates Fleas and Doesn’t Even Know It

Since the beginning of time, mammals everywhere have struggled in the fight against their miniscule mortal enemies known as Ctenocephalides, aka the FLEA.  These little bloodsuckers are by far the most common parasite of cats and dogs today and they are also one of the most frustrating for pet owners to deal with.  As much as we humans dislike fleas, there is one species in particular that hates fleas the most – your cat!

Here’s why:

Flea Control

1.) Fleas are sneaky little devils.

They will jump onto your unsuspecting cat while they are sunbathing on the deck/patio and wait to be carried inside your home. Even if your cat is outside on the deck for 5 seconds of the day they are at risk.  Once a flea makes it inside, they will lay approximately100 eggs per day in your carpets, rugs, and even your bedding.

Outdoor Cat

Not even the stealthiest of outdoor cats can hide from fleas!


2.) Fleas are disgusting, vile creatures.  Baby fleas (aka larvae) grow by feasting on their parent’s feces (yuck!).  As if that weren’t gross enough, mom and pop survive solely by sucking 15 times their bodyweight in cat blood per day.   In heavily infested homes, adult fleas will even bite humans and cause an unsightly skin rash.

3.) Fleas are (quite literally!) disease-ridden, filthy, blood sucking parasites.

Have you ever heard of tapeworms? These giant worms are about the length of a cucumber and live inside our digestive tracts, consuming food as it passes them by.  Dipylidium Caninum (aka the flea tapeworm) especially like to pray on our kitty cats and young children and are transmitted by fleas – gross!

4.) Fleas are NOT hypo-allergenic. In fact they are the opposite of hypo-allergenic.

Fleas can actually cause your cat to develop allergies. Their saliva can cause a significant allergic reaction within the skin following a bite.  This results in an intensely itchy skin problem called “Flea Allergy Dermatitis” or “FAD”, and is by far one of the most common dermatological issues in pets.

5.) Fleas are like teenagers at a high school party.

If you “shut down the party” by treating only one pet in your home the fleas will just move the party to the next available location which is often another pet in the house hold.  This means that if you treat your dog for fleas but your indoor cat is left untreated, the cat will likely be the host of a not-so-fun “flea party”

The best flea treatments are prevention.  Veterinarians at Royal York Animal Hospital are constantly reviewing products.  For cats,we recommend a product called Revolution, which is topical (applied to the back of the neck) and is only needed once per month.

6.) Fleas just can’t take a hint when it’s time for them to leave.

Most people don’t realize it that it takes 90 days or more to fully rid your home of all life stages of fleas (ie adults, eggs, nymphs, and larvae).  It’s easier for your and your cat the prevent the problem then to treat it.

THE BOTTOM LINE: Cats hate fleas. You hate fleas.  Fleas are gross.  Prevent fleas by treating your cat with a product such as Revolution if it goes outside  (even just a little).  If you have questions regarding fleas or flea preventatives don’t hesitate to contact us today at 416-231-9293 or

Even some condo cats (such as Dr. Zach's cat "Spanky") will require flea preventatives - depending on who they share the condo with !

Fleas and Tapeworms in Cats

By Cat Fleas, Pet Parasites, Tapeworms

If my cat has FLEAS then why would my vet recommend DEWORMING as well as treating for fleas???

The answer lies in the life cycle of the common flea. Fleas can act as an intermediate host for tapeworms ( Dipylidium caninum ) This tapeworm that infects both cats and dogs. Immature Fleas become infected after ingesting tapeworm eggs ( which can be from the ground/carpet/animal sleeping areas). Once these Fleas become adults,  they then can be ingested or swallowed by a cat or dog.  This usually happens when your pet is grooming or licking themselves. The result is a Tapeworm infection in your beloved pet.

What are the signs of tapeworm?

A pet owner usually sees visible segments around your pet’s bum area or fur in that general area!!  Sometimes you may see segments on top of your dog’s poop. These look like pieces of white rice. You may see several or just one. This is why whenever fleas are found on a family pet during a physical exam, we always advise it is best to treat for the fleas along  deworming  for internal parasites just to be safe. It is never harmful to deworm your pet (even if tapeworm is not present). If you wait for segments to appear, an infection is already established! INDOOR cats can be potentially exposed to fleas and tapeworm through contact with mice inside the home. Tapeworms  can also be transmitted to humans.
