Haven't tried it. Her conversations with me are usually polite requests for attention, such as when I am in my neighbour's house she will come in and indicate that the coffee break is over as I am needed at home. Skype wouldn't work for her but I would miss being ordered about.
I think the difference between cats and dogs are that with cats it's like I'll talk to you when I feel like it..and with dogs it's like I'll love you forever and ever and ever.
Brucie can give me eye contact and understands my facial expressions in the mirror. (I found that out by chance as we were walking down the stairs)
I grew up with a cat, had 2 cats of my own whom I loved very much..but my doggie love is so very different.
I'm glad you have a loving/sassy pet.
