I strongly recommend you talk to a professional or someone highly educated in essential oils and herbs before taking this route into your own hands. It’s crucial to know which oils are toxic to you at certain levels and I will say this in advance: Tea Tree Oil in ANY strength is toxic to dogs and cats. If they come into contact with it, you will pay the ultimate price with their life, so if you’re going to use it for any reason, keep it far away from your pets.
