Yes. Homescape products are 100% natural. As such, there may be natural color variations in the oils and herbs. Our herbal tinctures (Daily Thrive and Restful Pet) have real, whole powdered herbs in them which will settle to the bottom of the bottle, and if undisturbed for extended periods, will require more vigorous shaking before giving to your pet. You may notice herbal sediment sticking to the dropper. This is normal and simply requires vigorous shaking to mix the product. Companion’s Best Day will only vary in color slightly as it has little to no remaining plant material as the result of the extraction process.  Mussel Mobility and Mussel Mobility Complete can range in powder consistency and colors from tan-orange to reddish brown, mostly due to the turmeric.  If you are concerned about a product you have received, please email us at info@homescapepets.com. We will be happy to assist you.
