Alright, So three days ago i told my roommate to go to the vets and pick up some advantage to de-flea his cats and dog. He made the mistake of being cheap and had gone to walmart to pick up some hartz flea treatment. Last night at 2a.m. i saw samcrow out side, my roommates cat and he looked like he had been struck by a vehicle. The cats body was covered in mud, he looked cold and i honestly thought he was going to die. but when i brought him inside i placed him down on the counter to examine him. I did not see any cuts or scratches. His body was not bleeding, So i figured he was just cold, maybe he fell in a puddle and was freaking out from shock. I found a large towel popped it in the dryer to warm it up and wrapped sam up in it to see if he would stop shaking. but it was not working, i then noticed his body was not that cold at all. I was extremely scared, so i rushed sam to the pet emergency the whole time he was shaking would not open his eyes, and looked like he could not control him self. When i got to the vet, i told them that at first i thought he was struck by a car but he does not look injured, then i told them how i thought he fell in water but he’s not cold. they made me wait for about 20 minutes and came out and asked me if i gave sam any flea treatments, i called my roommate he said yea he used hartz flea and tick removal. Sam is still at the pet clinic. and they said he may make it and he may not. What i would like to know is, why on earth would any place sell this product, especially when most pets almost or have died from it?
