Spooky Expierience. Overlooking Or Something Else?

This might just be me overlooking something, or it could be something else. I'm not sure.

It was a Saturday morning and I was about to do my sister's hair. My mom was with my foster brother, Gabriel, at the doctors, so I was in charge. I had to get detangling spray and a comb. I walked into the bathroom, and picked up the first bottle of spray--It was almost empty. I threw the bottle in the garbage can and went back to the counter to find a different bottle. I picked up the 2nd bottle; this was empty also. I chucked that in the garbage and found that I needed to use the toilet.

As I do my business, I thought about getting the bottle of spray that was downstairs in the pantry. I flush the toilet and walk out of the room. I went down the stairs and into the laundry room. I walk over to the shelf and search for the spray that I had put down there the night before. I found that it wasn't there. I ran back upstairs and into the bathroom. I sat down on the stool and pondered. How could we run out of spray that quickly? Out of nowhere, my cat sprints out of the room hissing. I turn around instinctively, and sitting there on the counter was a bottle of spray.

It was full. It was the spray from downstairs.

What happened? Did I simply overlook the spray? Why was my *cat acting so strange?

*My cat stays away from the bathroom area and the basement now, but she never did before.
