Two of my 3 cats are acting strange after I had recently moved to my house some furniture that had belonged to my late parents. One cat will lay for hours in front of a dresser that use to be mine as a child and that my parents had kept for about 70 years. In that dresser are items from my parents house. This is the same cat who will cry in the hallway while walking past a library table from the 1800's. I had another cat years ago who did the same thing regarding that table.
Another cat will dash past the dining room as fast as he can after I had brought into the dining room a bookcase that my Dad had built for me as a child and that was also kept in my parents house for decades. And in that bookcase I had placed many of my Dad's old books and photo albums.
Being the cats were feral they really never bonded with my parents. My parents would visit on holidays and birthdays, so it wasn't like they were in my house on a regular basis. But I would be at my parents house, so I knew I would bring home the scent of their house.
The scent of my parents old house is on the furniture, on the books, on everything I had brought back to my house. Now I wonder if pets can sense something had happened?
