DD wants a pet rat. I wouldn't really mind, but right now, we have two pain in the bottom guinea pigs. They are not at all playful. DH's cousin has a rat. At first I was freaked out, but after a few times of visiting, I found out how cute and friendly it was. The only thing I don't like about rats, are their tails. There is something really reptilian looking about them and it freaks me out. But, that being said, when the guinea pigs are gone, I would consider a rat. I would NEVER get a spider or a snake. I'm terrified of spiders and DH is the same way with snakes.
