Why Does My Cat Still Scratch After Using Advantage?

I used advantage and it never seems to work. The cat is still scratching. I got it on the skin. And it's been longer than 24 hours.


If your cat had any sore spots from the flea bites then the spots could still be itchy (until they heal).


You might want to give it some more time or just get a different flea killer.


Because it depends on how badly infested the cat was to start off with,but it does take longer than 24 hours,it takes our cats at least 3 days before they stop scratching as much,another thing if the house hasn't been treated fleas will hop back on and bite,but wont live long but long enough to irritate,

so treat home and wait a few days,oh and fleas can cause dermatitis allergy so can cause itching too.
