I do, I send emails all the time with pictures, and cards during major holidays via snail mail. Also, I call Tiger's breeder, Sheri, a lot. She answers all my questions, which has been tremendously helpful in research for my book.
Sheri also doesn't work, so it's easier to just chat with her on the phone.
Angie, Rhapsody's breeder, responds to my emails, but I know she's really busy (works part-time, has 1 daughter graduating from High School, and 2 in Junior High) so I try not to bug her with phone calls.
