I had no idea about the terrible side effects of hartz flea and tick treatment. After finding a few fleas in the house I gave my wonderful cat jake a treatment and shortly after everything started going wrong. He’s twitching uncontrollably, his balance is off and he’s very confused. He is also biting his own feet vert hard to the point that the bleeding badly. I’m scared for him and I’m currently calling vets and begging them to treat him and allow me to pay in payments but iv had no luck.. I hope jake pulls through this and I hope all the creators of this poison know that they will one day be judged and harming gods creatures will not make him happy. May you all suffer the same fate as my poor cat. God willing.
