How do I know if my cat has fleas?
There are many signs that a cat has fleas. Here are a few.
You can see Fleas on your cat
Put your glasses on, grab a cat (gently) and go to a well lit spot. It helps if someone is there to distract the cat while you look for fleas.
There are several spots that are good to check for fleas. Any area such as around the tail, where your cat can't scratch should be checked. In particular the lower back and base of the tail. You have to move fast because the flea moves very quickly in the hair. If you don't know what a flea looks like check out the "what do fleas look like page". You might only see something moving through the cat fur very quickly. Another good spot is between the legs and in the cat's armpits or where his armpits would be if a cat had them. The whole belly area should be checked. Fleas can be reddy brown to black.
If your cat doesn't mind taking a bath, then give puss a bath and check the head because fleas will usually find their way to the top of the head where things are drier. None of my cats like baths so that's not a good option.
Sometimes if the cat has been away for a while and comes back to the home after holidays for example, then you might see fleas jumping on you or the cat after a day or so. Fleas emerge from their cocoon very quickly when they feel there is a cat around. The pupa waits till it can sense a cat and if you were away it might have waited.
What other signs are there that my cat has fleas?
Checking for flea dirt on your cat is a good way of confirming a flea infestation
Flea Dirt is the dropping of mature fleas. This flea poo looks like little black grains.
When a flea feeds on a cat the droppings are left on the cat and this flea dirt can fall on the cats bedding or anywhere else the cat sleeps.
it's very easy to check for flea dirt on a cat. Put your cat on a newspaper and ruffle his fur backwards and forwards. This will make any flea dirt fall on the piece of paper.
To check if the black spots are flea dirt rather than just old fashioned dirt you cat picked up rolling around, take a wet paper towel and wipe up the specs that fell on the newspaper. If the cat has flea dirt then wetting it will make the spots red because of the high blood content. If the spots stay black then they are not flea dirt.
You can wipe the cat's bed with a damp paper towel and check it for bloody spots.
Many cats have flea allergies
If your cats has lots of little sores in front of his tail then it is very possible he is allergic to fleas.
Feline Milliary Dermatitis is sometimes caused by cat allergies to flea saliva. One single bite can trigger the reaction.
It's possible for your cat to have a very low level of flea infestation where you cannot see any adult and there are not enough fleas to make flea dirt for you to find. If the cat receives only a small number of bites it can still react.
In that case you might want to check with your vet to confirm that there are fleas, even in tiny numbers. I have a page on cat allergies.
Another sign to watch for is scratching or excessive grooming
A cat that has fleas is not a comfortable cat and will scratch and bite his fur energetically. If you see your cat doing this then suspect fleas even if you don't find any signs. Itchy skin can be a sign of allergy but biting the sides is usually a cat after fleas. An energetic healthy cat can reduce his flea load by 50% by active grooming. Kittens and older cats are not so successful.
Some cats will groom to excess if they have fleas. This and scratching can cause sores or hair loss.
Anemia is a possible result of flea infestation
If you keep an eye on your cat it is unlikely that it will have so many fleas that it becomes anemic from blood loss. Kittens are more likely to suffer from anemia than mature cats. So check your cat regularly. A lethargic listless cat with pale nose and gums could be anemic.
So what's the next step?
If your cat is flea free, doesn't go outside and you can find no sign of flea infestation, and no scratching then you are lucky, and so is your cat. Keep an eye on it, keep the bedding vacuumed and check regularly. Why treat a clean animal?
If you suspect an infestation because your cat is scratching or has sores, but you can't find anything, then check with your vet to see what he or she suggests. It is not necessarily fleas.
The same goes for a listless pale cat. Suspect fleas but check with your vet before treating a potentially sick kitty.
Don't randomly treat your cat. There are several products available from the vet that are much safer than what you can buy at the pet store. NEVER USE DOG FLEA PRODUCTS ON A CAT. Cat are not capable of getting rid of poisons very well and you could kill your cat.
If you have found signs of fleas on your cat then you need to take steps to control the fleas.
If your cat is an outside cat or you have dogs that go out then it is unlikely you will get rid of fleas completely. You can do a good job of controlling them though.Read my Flea Control Page
