Is there any point to cats?
I mean, cats are lovely and all that, but what purpose do they serve?
They think they are hard but they aren't. Well mine isn't anyway, I know this because I know of no "hard" creature that likes having its chin rubbed so often while lying on the floor with its legs in the air.
And whilst I'm sure they believe they are doing something important by sleeping on my bed every night, it really isn't necessary.
Dogs, for all their faults, do have the theoretical purpose of guarding your property (though even this can be a bit of a reach in some cases).
