Oh, I've always had dogs, too! I have a dog and a cat right now, and it's fun to see all of them interact. My cat loves to sit by Maui's tank and just watch him swim around. Maui seems to like the cat and will come right over and blow bubbles at her. It's definitely a bummer when you live somewhere that won't allow dogs. Good thing you are able to have a betta! They definitely are happier in the bigger tanks and you get to see so much more of who they are.
My lovely bettas are: Dagger, Egg, Salsa, Marble, Augustus, Miles
Puddles, Oz, Nate, Monkey, Picasso, Feng, and Maui
