Well, I don't WANT them, since I already HAVE mine... but I had always wanted ferrets, and finally got my two just this past September.
I didn't think I'd be getting a dog for another year, and then The Litter came along, so... I'll have growing ferrets and a growing puppy!
I HIGHLY recommend ferrets as an awesome smaller pet. Very kittenlike, hilarious to watch, and nowhere near as smelly as people think they are. It's really all a matter of washing their bedding regularily and NOT bathing them regularily.
Here's my two, Palom (dark chocolate sable boy) and Porom (white/black roan):
As for future pets? Not sure. A Big Floofy Cat of some sort is in our future, and I've always wanted an axolotl:
Weird, fascinating, tricky to care for. Plus I have no idea how I'd go about finding one for a pet, or if they're legal as pets. XD
