I just want to thank you, even though we have delayed shipping the cat meds 'Stronghold' got here just in time. I have 2 cats a young cat and an older cat. Neither one have ever had fleas but this year I noticed the younger one biting and scratching then I saw a flea on her white nose. I bought a flea application and put it on both cats...it did nothing and my older cat was not eating or drinking and I know he would have died soon. You saved his life. I got my Stronghold and applied it hoping it wouldn't be too late. It started working instantly and it's been 3 days and they both are flea free and I've ordered another round for next month. I don't like to use it on them too often because the chemicals are hard on an old cat. I will always keep some in my house from now on ..thank you again. I appreciate you great products, low prices and fast friendly service.
