Thank you Martha for reaching out to us regarding our Flea and Tick shampoo formulated for cats and small animals. We understand when it comes to essential oils with cats especially, you must be very careful.
Cats are very sensitive to many different plants and flowers in nature, which is why when you look at the dilution rates of our products compared to the other brands on the market, even in the holistic options.
Elana and Sue have done countless hours of research choosing every ingredient in all of our products. You will find that we are diluting the oils in our products into the thousand to million percent, which makes them very safe and have proven to be non toxic to cats for more than a decade since we launched our products to the market back in 2008.
We hope this helps you understand that the ingredients we use are safe, natural and effective.
Thank you again for your question and I hope this helps you and others that read this to feel more comfortable choosing Mad About Organics products for their loving pet(s).
