Ask Seth: Cat Fleas

This month I put flea and tick medications on my cat as I always do and for the first time, it doesn’t seem to be working.   Any reason why now my pet has cat fleas?
The most popular reason topical flea/tick preventatives seems to fail is due to the owners bathing the pet just prior to applying the product. Many products work from within the skin's oil layer; if you wash the oils off, then apply the medication, it will not work! Most topical products are not repellants; they kill fleas and ticks on contact with skin oils that contain the medication.  Be sure to follow the instructions provided to make sure you are using the product correctly.

The other concern would be that you are treating the animal but not the environment.  Be sure that you treat your house and any area the animals spend time in too.   Flea eggs can be very stubborn in the environment and difficult to kill.   Speak with your vet about other options you can use to rectify this issue before it gets out of control.
