Can someone please tell me why my cat must get sick ON things?

Cause really, while cleaning up after her a couple of times in a single day (it doesn't happen *that* often) can be annoying it's ok. It means she's sick and not feeling well. It happens.

But doesn't she have to get sick on my bedroom floor mat???? Really??? Does she?

No, she doesn't. But she does and I suspect it's because she knows it pisses me off.  Damn cat.

Aside from cleaning up after my cat I've done next to nothing today. I'm tired.  I'm being lazy.
