My 7 year old cat had the shock of his life 5 weeks ago when we brought newborn DD home from hospital. He hid upstairs for the first few days, has eventually come down and we are making sure he gets a bit of fuss everyday. However, he has lost his purr. He used to be very purry but now nothing - has anyone else had this happen? He doesn't seem overly stressed in himself, is eating fine and will still let us stroke him so not sure what's going on with the purr. Thanks,
