Feels great when you’re able to save a stray momma kitty to be. It was coming up to winter and we couldn’t let her just live outside so we let her live inside but of course she had lots of fleas. Such innocence thinking you’re helping your pet by treating them with flea medication. WRONG. Not only did we apply this brand to the cat but also the dog. In a short week the dogs left side of his face drooped. His bottom eyelid hung so low we thought he had a stroke. Then the cat began to not move she would stay in one spot the whole day. Didn’t move for food or water. She passed away in our arms a few das later. This product is not safe. This product should be taken off all shelves.
