"...If all the animals disappeared, man
would die of a great loneliness of spirit."
- Chief Seattle, 1855
Animals respond well to Reiki. Just as in humans, Reiki can be used for all types of illnesses, injuries and emotional problems. Animals enjoy Reiki - the extra attention and feeling of the energy draws them to the Reiki Healer, who sends Reiki via simply patting, stroking or touching the animal. My own cat has been known to soak up Reiki energy like a sponge.
Treatments involving animals rarely last as long as human sessions; they absorb Reiki energy a lot easier than we humans do. Usually, they will not sit still for an entire session - rather they receive Reiki for a few minutes, then wander off, only returning again a few more times for more healing.
Since Reiki can also be send effectively from distance, this means it can be used on animals with skittish or aggressive animals without distressing them or risking injury to them, their keepers, or the Healer herself.
When treating animals, it is usually best to conduct the healing session in surroundings that they know and feel safe in.
