My pet of choice is anything my partner will take care of without me having to share any of the responsibilities... oh wait, that pet doesn't exist?! Then NONE of them, tbh!
I guess I would defer to cats over dogs based on that whole self-reliance thing, but something about the weekly snake feedings always excited me too.
I like the feel of snakes, but not sure if I would enjoy a pet one. Dogs (smallish ones) are great. I wouldn't want another large dog though.
I was talked into a 2,5 kg Yorkshire Terrier by my first wife and she was a good girl named "Martini." She was fine, barked a lot bigger than she was, and her most redeeming quality was how much she liked to lick between my toes after I got off work. She is now 16 and still lives with mom.
