I'm not fluent in Cat, but to date it seems to mean:
1. I'm hungry, feed me.
2. Let me out, I gotta pee.
3.
Nevermind, I just peed in your potted plants in the living room and sprayed your favorite recliner.
4. Let me in, I'm sorry. I'm done peeing.
5. Your in my
chair.6. My ear itches, scratch it for me
will ya'.
7. I'm soooo glad your home, I missed you today. (See examples 1 and 6 for reasons for being missed).
