my cat of ten yrs died 7-14-14 after I put hartz flea collier on her.i cried all night.my dog and other two cats started acting strange I removed there colliers. they are doing a little better now. you people need to check out what you are doing. you are killing our pets.
I just lost my two cats within 8 hours of each other because of the Hartz Ultragaurd home spray. THIS HAS TO STOP.
