I happened upon this site because I had done a search on hartz flea product’s. My cat of 5 year’s has just become infested with flea’s. I am stuck between the decision of using a pesticide flea treatment or letting my poor baby suffer the blood thirsty wrath of these flea’s. I am worried the flea’s will eventually kill her. Can someone please advise me as to what route I can take to effectively cure this problem with the utmost safety. If I lost my baby I would be heartbroken forever. I am so glad I found this site before hartz poisoned my baby to death. Thank god for site’s like this one.. Please help if you can this is an extreme emergency..
