Also, heat tends to bring out smells, so if it was warmer in the house when she was there she might have picked up on that.
The only time I ever told a friend that her place smelled, was when she had 2 guinea pigs and 2 rabbits in her small bedroom. She asked for my opinion, and I told her it might be a bit much, so she rearranged her animals.
