Why I am anti "new animals" in the house

Small Gray Cat here. Some have asked why I am so stringently against the introduction of new animals in my home. Indeed...I'd like to get rid of a few. But why the vehemence? Why must they die (see exhibit A: dead mouse).

Well, first of all there is the matter of resources and space. There is only so much space available on the bed. Even if I were to be successful in my attempts to asphyxiate mommy, I would simply expand to fill the space next to the boy. Moreover, that fat cat always takes up space and seeks out my hiding places. And eats all the food! More animals will only take up more room, eat more food and distract the boy from what he should be doing: giving me attention.

But it's more than just that. Let's look at mommy's track record in adding new animals to my house. First was the awful tuxedo cat - enough said there. Then that horrible boy cat whom nobody liked. Then the loud/crazy dog who upsets me when I'm trying to get pats and attention. And finally that neurotic dog in the new house. When the mouse showed up, I knew that direct action needed to be taken - I eliminated the mouse. I will do it again. This is not a threat - it is a promise!
