Flea/Tick Begone

I have tried the expensive brand of flea and tick treatments, and Hartz works just as well as the other. Be observant that your pets can tolerate any medication given or applied to/on them.

I have cats and they were getting what I thought were scratches from cat fights. but when I saw that they kept on biting and licking and hair was going everywhere I research and saw that it was fleas and larve...eeewwwww..I tried everything. the shampoo, the cheaper version of this...and something very expensive that did work within 30 to kill the fleas on them but it didn't attack the larve. I was sad. but I tried one more time and got this...and it works ..well on mostly all the cats cept one. but he's doing better too just maybe didn't catch it in time for him ..as for the others...no fleas really and for sure sure those pockets of larve eggs are all gone. so yea...I'm ordering it again and once the 1 cat gets seen at the vet I will be using these on him too from now on...the price is right and it works the best out of all I tried...
