I vacuumed my car the other week, drove to Portsmouth, sailed to Spain, started the car and the SRS light came on, it stayed on for a couple of days, I then wiggled the wires under the seats and it cleared.
However with your car my first guess would be that the rabbit damaged the sensor or wiring on that side, have a gander (a look, not a swan
)on both sides to see if anything is amiss.
