Been struggling with money to get rid of the fleas that all 3 of my cats have. Seen hartz in Walmart for $5. So thankful for this site. Luckily I looked up reviews before putting it onto my cats and was taken here. I could’ve lost all 3 of my babies that are my everything. Something needs to be done this is ridiculous. Reading all this stories makes me chest hurt. This cant continue. Pets are children to people! Its heartbreaking when youre just trying to help your animal and then this!
