You racking it and moving it into the cabinet are two reasons that co2 could be coming out of solution, usually from the trub...doesn't mean you do or don't have fermentation, just that you've disturbed the integrity of the liquid, and co2 is being released.
Changes in temp, barometric pressure, the cat knocing into it, racking it, moving it, ALL can shake co2 loose.
I wouldn't worry about it.
