Be careful of this PRODUCT…If you use it , use sparingly and not recommended duration. I think with more time and extra bathing. I think this product caused the DEATH of my BUDDY. A long hair tabby of 11 years old who was in GREAT HEALTH. (ELVIS)..In the last few weeks his normal activity changed. He went into some hiding and eating less…This yesterday morning , he walked in like he wanted to run somewhere. He turned and fell to the rug and seizured DEAD like with a heart attack and body shutdown.I was stunned ; I tried some mouth to mouth but total no movement. It was like instant DEATH ; but this was after a few weeks. A total healthy ADULT CAT ; in a few weeks; GONE !! This product may kill the bugs ; but it KILLED my loving cat !!!
