Shrews

I find these creatures interesting. They are closer to Elephants than rodents. They are often very tiny and very vicious. They also usually have potent saliva.

I love Cats, but even though I am a cat lover I still think that they can be creepy; for instance: when Cats look off into space, they tend to seem to be watching something, like they see an unseen presence.

Cats will chase things; even if there's nothing there...

And third, Cats tend to be silent, with staring eyes; one minute you think that you know where it is, and the next It's on your sholder.
