Dee-
  I know exactly what you mean. It's not purring, but more of a 
trembling (or vibrating) kind of thing. Molly has done that twice. 
Once the 1st night I held her because she was scared, & one night when 
her belly didn't feel good. I don't know why both your piggies would 
be doing it though. Maybe others can help shed more light on your 
issue, but I know exactly what you're talking about. Keep us updated.


***JAIME***, Molly the new pig in town! & Albert always in my heart.
