Fleas are small insects which are just visible with the naked eye. They commonly infect many wild and domestic animals. They are a problem to animals and humans by their need to feed on blood and therefore their need to spend part of their life-cycle on a living creature.
Although there are different species of fleas, it tends to be the cat flea (Ctenocephalides felis) which causes most problems with both dogs and cats! Pictured above (highly magnified!), you can see the powerful legs used for jumping huge distances and also the sharp piercing mouth-parts used for sucking blood.
As explained above, fleas need to suck blood to obtain their nutrients required to survive and reproduce. Most of the problems caused by fleas are caused by either their presence on the body or the act of sucking blood. A range of signs can be seen with animals affected by fleas. These can range in severity from mild irritation, itching and scratching, to marked irritation, hair loss and self trauma. In extreme cases some animals may even become anaemic due to blood loss caused by large amounts of fleas feeding on the animal (70 fleas will ingest 1 ml of blood a day!)
Some animals are actually allergic to the flea bite (actually the flea' saliva is thought to be the culprit) and this can make matters much worse as it may only take 1 single flea to trigger an allergic reaction. Fleas can also be responsible for the spread of certain blood borne diseases and parasites. To name just a couple, fleas can transmit a particular type of tapeworm (Dipylidium caninum) to dogs or cats, or cause a condition called Haemobartonellosis in cats which is an anaemia caused by a parasite which destroys red blood cells.
Often the first sign you see are signs of irritation . Fleas should always be considered if your pet starts to scratch. If you part the coat so you can see the skin - you may happen to actually see a flea. They are very small, move very quickly and often jump as soon as you see them. More likely you see the presence of "flea-dirt", which is tiny little black specks just visible on the skin surface. Flea-dirt is actually the faeces of the flea containing digested blood. If you see this, then it is very likely that your animal has got fleas.
The life-cycle of a flea is quite complicated. Believe it not, when there is a flea problem, what you see on the animal is only 5% of the total flea population - the other 95% are on the ground (often in your house!) Fleas need to feed off a host animal in order to reproduce and lay eggs. Within hours, these eggs will have dropped off the animal's coat onto the floor where they hatch to form larvae. These tiny, maggoty like creatures are highly mobile and are afraid of light so crawl into carpet pile, under furniture etc, where they feed off organic debris such as dust and skin flakes . After a short period of time these larvae form incredibly sticky cocoons (about 5 mm long) where they develop into adult fleas, which emerge after a few weeks. These new adults are going to be hungry and therefore actively seek out the source of a meal - your pet. Hence the life-cycle is complete.
This means that animal to animal transmission is quite unusual and that most infestations will occur from contact with an infested environment.
As with many other conditions - prevention is better than cure. There are a number of prescription treatments/prevention for fleas available only from your vet. These are very effective, safe, and often have a residual action so will prevent the animal becoming re-infested for a period of time. These come in a variety of forms, such as sprays, injections or spot-on pipettes of liquid that you can apply to the back of the neck. As well as treating the affected animals you should also:
We have access to lots of different types of EXCELLENT control - including spot-ons, tablets and wearable preventatives.
If you are concerned about fleas, one of the vets or nurses would be happy to give you any further advice that you may need. Don't panic - as even those animals that are kept in the best and cleanest conditions are still likely to get fleas at some point in their life!
