I'm a "cat person" also. Maybe we are all just "animal people?" I like dogs too, but I like big dogs and live in town. No running room, I won't chain a dog up, so no dog. I do have four house cats. They never go outside. While the neighbors wouldn't eat them (I hope) my house fronts on a very busy street and they would be roadkill if they were out wandering around.
The other part of your post is interesting. My cats are so low maintenance in comparison to Timber! Other than the routine stuff like feeding, scooping litter, watering, my cats will let me know when they want a good scratching or they just park on my lap and sleep. They are very independent otherwise. I had no idea when I got Timber of the difference in time and effort that goes into being a bird owner. I don't know what I thought, but I had no idea how needy they are when it comes to time and attention. Timber really makes me happy though, so it's all good! His neediness meets a desire I have to feel needed I suppose.
