I had fish as a kid (around 7 or 8, I think), which was a horrible mistake. Kids should never have pets, imo, I know I failed them and they all died horribly. I had one male betta for a pretty long time, and decided to get a female one - I knew they were "fighting fish", but I thought males would only fight males, so I put the female in the same tank and shortly after the male betta killed her. Afterwards he just kept jumping out of the tank. I put it back once when I found him on the floor but like a day or two later I found him all dried up on the carpet again. :( I haven't owned any fish since then, I felt so bad after that.
That was really morbid. On a lighter note, I am totally in love with this cat. If I didn't have a jealous 14-year-old dog I would've taken her home.
Her name is Molly, but she's been renamed Tessa by her adoptive folks. One of the sweetest cats I've seen in a while, she loves to be held and to play with people.
