Last year I used a reputable flea & tick spray, that I purchased at the vets, on my cat who is 12 years old. I nearly killed her by using this. Her kidneys just about gave out. Is there something else that I can use without harming her? Will Frontline cause the same problem? Deer ticks are a large problem where I live.
I have not seen any reations to frontline but I can not tell you that she will not have one for sure. vetcare
