What is a better pet to have?
Depends on who you are I think. Like personality wise. If you are a relaxed person: cats. If you are a more fun energetic person: dogs.
I do not believe one is better than the other. I believe it depends on who you are really. There are many sad situation's of animal's being placed into homes that they are uncomfortable in. It effects the animal in many ways. Also depending on how close you are to animals it can effect you as well. Animals where never meant to be pets, but companions.
