I don't know about you, but I have a sweet cat who helps me with all my readings. He senses the energy shift in the room, jumps on my lap, and "inverts" himself. Aside from the purrs, I can feel energy pouring off of him in waves. He is the epitome of the familiar. He is sensitive to energies and always wants to be right in the middle of them.
For the past few years I have started asking my guides to convey messages to my animal friends. It seems to work better than getting all worked up over some naughty behavior. It's especially useful when I encounter new animals. "Please tell them I'm not a threat," is my go to phrase. More often than not, the animal relaxes. My guides are very good with animals!
Strength inverted can indicate the healing power of touch, the awakening of your inner, magical power, and working with animal allies. Animals can be powerful allies simply because they aren't hypocritical. They sense and react to energies without passing them through the human filter of appearances. The Universe honors honesty, and animals offer that. Tuning into the energies of our familiars, no matter the species, transforms our energy into something more pure. It brings us back to the natural cycles of life. Once we're realigned with the earth and all her creatures, we can find our own inner magical power.
