Product delivered quickly, and for a fantastic price. I've used Advantage in the past and highly recommend the product. Our inside cat gets to go outside every now and then, and in Florida, we have no 'down season' for fleas, they're rampant pretty much all year round, but we never see any on the cat. When we moved into our current place it had a flea infestation in the garage due to previous tenants, but my cat didn't get ANY, even though it took us several weeks to kill them all. The stuff works. Buy it.
