Please someone tell me if what I think happened actually happened. Last night my 11 month old cat started putting her butt in the air being really cuddly. It was pretty subtle though. This morning she jumped out a window and I couldn't find her before I had to leave. I came home 6 hours later and didn't see her but there was a strange cat in the yard (tom). I called her for about 10 minutes and she came out from under the woodpile. The Tom was in there as well. It took me a couple minutes to get her to come to me. I brought her in and set her on the floor and she flopped down and stretched out on her side and rubbed her face all over the floor. She's never done that before. She was kind of chirpy and purring. Seemed very happy. Then the butt came back up..she has been sleeping for awhile now. So..did she do the deed and could she be pregnant from just one time?
