15 ml / .5 fl. oz. There are approximately 300 drops of essential oil in a 15 ml. bottle
I diffuse this oil blend to keep my hedgie calm, socialized and happy (he chirps!). This 15 ml bottle contains 100% pure therapeutic grade essential oils of Lavender, Helichrysm and Frankincense. You can purchase each of these oils individually; however, Helichrysm and Frankincense can be quite pricey so I blend the oils so you would not need to purchase all three. I also use 2 drops of this oil blend on a dryer ball when I wash Maxwell's bedding.
Recommendation: Use 1 drop in a diffuser to see if your hedgie likes this blend. If not, discontinue use. Depending on the size of the room and your diffuser, you may be able to diffuse 2 to 3 drops of this concentrated oil for your hedgie. Keep it safe and don't overuse the oil - the dilution rate for a hedgie is less than that for a human.

Please keep your hedgie safe and only use 100% pure therapeutic grade essential oils. Absorbing or inhaling synthetic chemical and impurities can be unsafe, and will most certainly negate the therapeutic benefits.
