No! You can’t use the same remedy for humans and animals.
There are different requirements to flea spray for humans and cats or dogs. You may hurt yourself with pills or sprays for cats. Even homemade remedies have different recipes for pets and their owners. Cat’s fur and human hair, as well as humans’ and animals’ skin, are different. I suggest you check out collars for cats to prevent fleas, and skincare remedies and anti-fleas shampoos for yourself.
