My local vet’ used profendor de-wormer for cats on my kitty Squiggy. She was fine and then passed away. I have already spoken to one lawyer regarding this and they denied my case. I loved that little kitty SO much and I still have trouble sleeping without her or having her attack me from nowhere. She was just playing with momma. I have done a little research and please correct me if I am wrong, is Hartz a subsidiary of the Bayer corporation? I am so confused over all this and it may just be the grief. I miss that little girl so much. That vet’ evidently doesn’t do his research before using these medications because I have come across more than a few complaints over this product. Thank you and blessings to all those that are grieving over their furbabies passing due to someone else’s incompetence.
