Good advice Aldiaz, I'm off to check my smoke alarms now!!
Condolences to you and your family. I can only begin to imagine what your wife must have gone though, we leave our two dogs indoors too when we're not home and the thought has crossed my mind before of what would happen in a fire, it really would be a nightmare come true. At least your wife and daughter made it out, I'm sure given time they will recover from the stress of such a tragedy.
