Could it be because they are all terrorists at heart.
They wage an unrelenting and merciless jihad against the furniture.
They wake you up early in the morning because they want you to wait on them or just cause they want company, or think, in that twisted little cat mind, that it is 'time to get up'.
They demand that you stop whatever you are doing because they want attention.
My cat demands that I get off the internet and go to bed when she thinks it is time for everybody in the house to be sleeping.
When I really want to see a TV show, my cat hops on my lap, demands a tummy rub and then goes to sleep...thus knocking me out....and so I miss the show. Well, can you stay awake with a sleeping cat on your lap??? Huh?
Cats are demanding, they want something, but don't know what they want. Hmmm, they are just like women.
Finally, my cat talks. No, she argues. I say something to her and she replys in cat talk. This can go on for a long time. If she wants something she is very vocal and demanding. Other times she has a long list of complaints...all in cat talk. ( sort of like a wife or ex girlfriend. )
Thank God for airsoft BB machineguns.
