Boo makes herself comfy as she awaits her person's return.
This is my mother's feline companion, Boo. Boo is quite shy and spends her days in my mom's room. Recently my mom went to London for a week and we were talking about how Boo really misses her human when she is away and how sometimes she exhibits that stress in unladylike behavior.
I told mom to try something that I read in one of my Holistic Cat books. It seemed to help Brendan the last time we went to Europe for two weeks. Brendan used to get up in the middle of the night and howl sometimes. He was with my in-laws during that trip and they said he howled every night except for the one when we were getting on the plane in Zurich. He was calm that night as he waited for our return.
So. Sit with your cat and tell her you have to go away. Imagine how sad you are to be leaving her and how you don't want to leave her but you must. Imagine a picture of your return and how happy the two of you will be. Imagine an image of each night you will be away. Imagine the nights one by one. Beam these thoughts into your furry ones little head and send comforting thoughts of your return.
Mom did this and said Book was much better while she was away and happy at her return.
So give it a try and let me know if it works for you next time you have to be parted from your loved ones.
