Ticks and Tick Diseases
Feline Heartworms

   
The Truth About Ticks

Ticks are Not Insects
Ticks are eight-legged, wingless parasites related to mites and spiders. ticks do not fly or jump; they wait for a host to brush against them.

Even Immature Ticks Suck Blood
There are four stages to the tick life cycle: egg, larva, nymph and adult. The larva, nymph and adult all suck blood.

Ticks Thrive on Free Rides
To feed, ticks attach themselves to warm-blooded animals and bite -- they do not burrow under the skin. After feeding, the tick drops off its host, molts or lays eggs, and then waits for another host. Many tick species feed on more than one host and can transmit disease between animals and humans.

Deer Ticks are Tiny
The deer tick, know to transmit Lyme disease, is about the size of a pinhead in its nymphal stage. Adult deer ticks are much smaller than the common dog tick.

Be Aware in Warm Weather
Ninety percent of all cases of Lyme disease are from nymphal-stage tick bites. This nyphal stage occurs during spring and summer.

The Mosquito Menace

Vectors of Heartworm
Canine heartworm disease is spread by mosquitos. It can be found throughout the world, wherever mosquitoes breed. After a mosquito bites an infected dot, heartworm can be passed on to other dogs that the mosquito bites.

Prevention is the Best Protection
The best way to prevent heartworm is to keep a dog from being bitten by mosquitoes.
 

One bite can end nine lives... Feline Heartworm Disease

Heartworms, which are spread by mosquitoes, have long been recognized as a dangerous threat to dogs. Wherever dogs are at risk from heartworm disease, cats are at risk, too. Unfortunately, the disease is difficult to diagnose in cats and dangerous - it can kill cats as well as dogs. Every cat exposed to mosquitoes may be at risk.

What are heartworms?

Heartworms are parasitic roundworms up to 24cm long that live in the right side of the heart and adjacent blood vessels. They survive on nutrients in the cat's bloodstream.

How can feline heartworm disease harm my cat?

Even a few adult worms in the heart can block the blood flow and cause damage to the heart, lungs and liver. Heartworms can also move to the cat's brain and spinal cord. The damage to internal organs can be so extensive that death can result. As few as two heartworms can kill a cat - often with no warning.

How do mosquitoes spread feline heartworm disease?

Heartworm lifecycle

  • The cycle begins when a mosquito bites an infected animal and picks up immature heartworms from the animal's bloodstream.
  • During the next two to three weeks, the immature heartworms develop into infective larvae inside the mosquito.
  • When the mosquito feeds again, it transmits the infective larvae into the healthy cat.
  • The larvae penetrate the skin and develop within the tissues.
  • The young worms then migrate to the heart.
  • Once inside the cat's heart, the worms mature and cause damage and even death.

What are the signs of feline heartworm disease?

Unfortunately, feline heartworm disease may cause much of its damage before there are any outward signs of infection. Even a cat that appears healthy can die suddenly from feline heartworm disease. A cat with heartworm disease may show one or more of the following signs:

  • persistent cough
  • vomiting
  • general listlessness
  • troubled breathing
  • fatigue
  • collapse

What is the treatment for feline heartworm disease?

There is no approved treatment for feline heartworm disease.
