Hmmm. I'm having difficulty choosing between a pet rat or a cat. (Ha, that rhymes.)
See, a pet rat is risky because too many of them are kept alone in a too small cage or get fed to damn snakes. And cats eat mice and rats. And spiders. Ew.
I really don't know. See, now I'm gonna have sleepless nights lying awake pondering this stupid question. *sigh* Oh, the woes of being me!
