We have tried several dogs in the past, but they were too much for us to house train. We currently have a cat, yes ONE cat, and we love it! I agree with a previous post: cats do have a lot of similarities with hackers; and without any other local hackers to get together with it's nice not to be alone all the time. Plus cats are there for your all night hackathons!
We have had some other various pets in the past: Guinna pigs, mice, a bearded dragon and a few birds. But my favorite pet of the past would be...a rat. Yes, a RAT. But they are really good pets!
I currently have three dogs, a lot of fish in the fish pond (swordtails, mollies, guppies, angels, hammerheads, janitors, a pig nosed turtle, and an alligator snapping turtle. I also have a pair of bettas in a small aquarium, and two baby bichirs and three black ghost knife fish in a large community tank. In a cage, I have three leopard geckos.
I used to have a lot of dogs (mostly chihuahuas), four big flowerhorns, two even bigger silver arowanas, two fortune lobsters, a cage full of lovebirds, a tank full of white mice, a guinea pig, a monkey, a wild cat, and a maina.
