I love cats but am highly allergic to them now, thank goodness.
They are so intelligent it is scary. They are also vengeful.
I had a ten year old female, she was my sidekick, but if she got upset she'd piss and shit on the couch. The older she got, the worse it was.
I miss her terribly, but everytime I sit on my comfy clean and shit/piss free sofa now I really enjoy it.
and I am not scared when I say commands my dogs, worried about their reaction.... dogs are not as evil.
