ugh, I usually like natural stuff, but we just had a bout with fleas this summer with our 2 cats. They never go outside, so I was shocked they had them! But they can come in on you from the yard! After relentless flea treatments from over the counter, we tried Frontline once and within 24 hours the cats were not maniacally scratching. Many pet owners told me the OTC flea stuff didn't work well, as did the vet. I rather talked to pet owners that weren't profitting from me purchasing their recommendation, and I heard frontline, over and over. If you are worried about your house, it is well worth the extra $20 to treat the kitty. And the vet also gave us some spray, but comparing that to the dept store spray, it was comparable... dunno if this helps! Hope it gets better soon! Once the kitty leaves, the fleas won't have a host anymore and will hopefully leave!
I would spend the $ on frontline instead of a bomb though. Those things are very toxic to breathe in.... And if the kitty has eggs in its fur, which most likely it does, the bomb won't help. Again, I hate using chemicals, I am an herb freak, but my kitties had fleas falling off dead within less than 24 hours.
