Should I Get Another Hamster?

I don't know if I posted about it or not, but my Roborovski Dwarf hamster, Moot, died awhile back, and I've been thinking about getting a new small creature to love and care for. I was thinking about getting a couple of hermit crabs like my buddy did, but I found out that its consistently too cold in my house for them to live (plus one of her crabs ate the other one 0_o). I was gonna try another fish, but I don't have anywhere to set up a tank with a filter, and again its too cold in here to bring in another Beta fish (so sorry Betta-chan I lov-ed you and miss you). Then I found out that Chinchillas easily over heat, and love the cold, but they need to be cared for gently for they are extremly fragile and I can't trust the cats not to go after the little guy. Plus its over $100 to get one! O_O I can't have a rabbit cuz it would have to live outside, and that would be just too cruel cuz of the heat. And my mom won't let me get a duck, which by the way is the only bird I'm interesting in getting (I'm not too good with birds). And I looked into getting a snail, but they don't sell any around here except for the sea ones (I wanted a land snail).

So should I get another Robo Dwarf hamster? Or does anyone have any other suggestions. Keep in mind I have 2 extremly nosy cats (plus a cockateil, and a 15 year old chihuahua), and I live in Fl so it would have to be an indoor pet that cold survive in 68 degree temp.
