The few days following the addition to Gibbs in our home in November (from a local animal shelter) he had TERRIBLE gas. I'm sure it was from food changes (he was a stray and then in the shelter so who knows what he was eating). He is still quite a gassy boy. He gets bouts of gas every now and then to the point that we have to turn all the fans on in the house and his very playful sister doesn't want to have any thing to do with him. I too wonder about his gassy days it comes and goes...
