Out of my gang of three, Thumper is my barfer. She goes in spurts usually couple months inbetween and just for a couple days. Always in the early hours of a.m. when she gets up to eat when hubby gets up at 4 a.m. for work. Yep, she did it this a.m. She eats to fast and barfs. I keep telling her to slow down but Thumper has a mind of her own.
