Flea Anemia in Dogs and Cats
It is important to get the message out early: Fleas aren't just a nuisance. They drink blood, and blood loss can kill.
In almost every case, the owner had no idea that flea infestation could be lethal.
It is hard to imagine that something as tiny as a flea could be dangerous. It is common knowledge fleas can make pets itch. Many pet owners are familiar with the spectacular skin inflammation in a flea-bite-allergic pet, but many people forget that fleas drink blood and that lots of fleas can drink a lot of blood. The physical state of inadequate red blood cells is called anemia, and when it is severe enough, it is a life-threatening condition.
Pets will not itch from their fleas unless they are allergic to flea bites. No scratching does not mean no fleas.
It is easy to underestimate a pet’s infestation. Only animals allergic to flea bites will itch from their fleas. This means that the animal who is not allergic to flea bites will not be scratching or losing hair. Thus, an owner may not realize that the pet has a heavy infestation. If your pet is effective at licking and self-grooming, it may be hard to see the fleas, especially if the owner does not have a flea comb. Do not rely on your own ability to see the fleas; use reliable flea control regardless of what you see or do not see.
Check for Flea Dirt
The black, pepper-like specks found in an infested pet’s coat are actually bits of blood that have been sucked up by the flea and excreted in neat little packages to feed the larval fleas that hatch in the environment. Even if live fleas are not seen, flea dirt means that live fleas are there.
Who Is Most Vulnerable?
It takes a lot of fleas to produce enough blood loss to create a life-threatening situation for the host pet, but it still happens commonly. The following situations are high risk for flea anemia:
Very young kittens being raised outdoors or by a mother cat who goes outdoors. Young kittens are small and do not have blood to spare. Furthermore, they are growing and trying to expand their blood volume; they are too young to groom themselves effectively and remove their own fleas. Flea anemia is probably the number one cause of death in open-household kittens.
Elderly cats who go outdoors. The elderly cat is often debilitated from other metabolic problems. Grooming is less efficient, and an older cat is just not strong enough to withstand much blood loss.
Outdoor puppies' situation is similar to that of kittens’: too small to effectively groom and trying to grow in the face of ongoing blood loss.
Eventually, the weakness catches up with these animals, and they will die unless they receive a blood transfusion.
