Lessening Separation Anxiety

[wyldbutterflies]

In September, I will be leaving for Japan for a three and a half month stint to study Japanese. I will be leaving behind four cats - three of whom really adore me. Even though I am leaving them with their other mommy, I am still fretful that she may have to deal with their separation anxiety the for at least the first couple weeks.

I already plan to send them video with my voice attached from Japan so they can at least hear me every know and again.

Do any of you have any suggestions on how I can make this transition a little easier for my furbabies?
