Yes, Cat Fleas are the most common type of flea infestation found on Dogs.
Please be very careful when you have Dogs and Cats in the same household. Many owners have accidentally poisoned their cats when treating their Dog for fleas; or worse they have treated their cat with a spot-on flea treatment for dogs. A common ingredient of flea treatments for Dogs is a chemical called permethrin – this can be fatal to cats. Read the warning on this page for more information
http://fleas.bizorium.com/info/Cat-Fleas.php and make sure you always read the label on flea treatments - look for the chemical name permethrin.
As for the orginal question - yes it is possible for a Flea bite to cause problems in human victims, see this quote...
Quote:
“Flea bites on humans can have several consequences. The obvious one is two weeks of discomfort from where the bite occurred. This is easily treated through use of lotions and applications, and will cause no long term effects, unless you have an allergy to flea bites. If you have an allergy to flea bites, fleas can cause severe effects, and use of an epi pen or medication may be required.
In addition to this, flea bites on humans can lead to disease. Fleas, like many blood sucking insects, can transmit a variety of diseases to human prey. This can have devastating long term health consequences. If you have been bitten by a flea and notice symptoms other than swelling, itching and irritation, consult your doctor immediately. This may be a sign that you have contracted a disease from the flea bite.”
