Hello Sika,
I haven't found many, but in all my searches, this one seems to crop up the most:
Animal Reiki: Using Energy to Heal the Animals in Your Life by Elizabeth Fulton and Kathleen Prasad
Here's another one:
Hands-On Healing for Pets: The Animal Lover's Essential Guide to Using Healing Energy by Margrit Coates
Both can be found in numerous places for sale when doing a web search.
I haven't purchased either yet so if you get one and want to post a review, I'd love to hear your feedback! ;-)
Many blessings,
Mandy
