Today I noticed my cat had chemical burns from HARTZ Flea collar. All three of my fur babies had the collar on, thankfully it only affected him. Not saying I’m not devasted. I have no clue what to do, do I take him to the vet? Do I continue to clean and put Neosporin on the wounds? Thankfully it isn’t as bad as it could be. I just hate seeing my fur babies like this, it’s a shame. What this company does to our animals our loved ones. I wish more people knew about this brand. It isn’t FDA approved. I was already scared about the collar, but I figured why not give it a try. But now I know, Hartz is a no go. And they need to be sued.
