This is a horrible business!!! It is a scam… I bought a 12-month supply of Frontline Plus for cats from this company this past October for my strictly indoor cat. I used four months of the product and since it was winter and the fleas didn’t seem to be a problem, I figured I would stop using it for a few months to not waste the product. The flea problem became problematic again a few months ago and I have faithfully applied it to my cat once every 30 days as directed. I couldn’t understand why my cat was still scratching incessantly, spitting up hairballs(realized later it was from licking the bites), and I was finding drops of blood on our bathroom counter everytime he sat up there(later found out those were flea feces). Finally, two days after the 3rd treatment, I started to pick through his fur to figure out why he was still scratching so much. I picked off over 30ADULT, very alive fleas! Two days after the treatment, those things should have been dead, if not almost dead. I went to call the number on the Frontline box and found it was from Austrailia, so I couldn’t contact them. I called the US version of the company and they informed me it is illegal for any company to send over a foreign product of Frontline to the US. I had to fog my apartment, bring my cat to the vet for a flea bath, get more flea treatment and sprays… costing me close to $ 200.00. The vet told me that I was the third person in a week that shared about ineffective Frontline product that was bought online with an Austrailian box. I called Total Pet Supply and they said too much time had passed(I bought a year supply and it has not been a year) and they would only refund the last 5 vial — but take no responsibility for the rest of the product used(even though it was ineffective).
