Our cat, Sam, was acting really strange last night.
She usually keeps to herself, unless I'm sitting on the couch watching TV. Then she'll hop onto the arm of the couch and lie down. Last night I was at the computer and she wouldn't stop coming into the den and meowing. Or standing on her hind legs and rubbing her face against the arm of my chair.
I checked to see if she had food. She did. I emptied the bowl and gave her some fresh food and water. That occupied her for about 5 minutes before she returned.
I went looking for her toys in the living room, found 3 of them, and tossed them out into the middle of the room for her to play with. She walked over to them, batted one around for a few seconds and then followed me back into the den.
She eventually hopped onto my lap and draped herself over one of my arms and purred away contentedly. After 10 minutes of that, she hopped down and left.
I'm guessing that she just wanted some attention, but it's not very often that she acts that way. It was rather strange.
