Thinking of getting a new pet?

It's a small question on the surface, but quite loaded when you stop to consider it on a deeper level.  Many people who decide to purchase/rescue a new pet realize the importance of their decision and take certain factors into account.  This forethought is very much needed, however the full implication is still frequently underestimated.  I feel the decision to add a new pet to the family should be taken nearly as seriously as the decision to add a baby to the family.  Granted, these two things are on VERY different scales of responsibility; however the approach to these additions is nearly the same.  With any new addition, factors such as lifestyle, schedules, and finances are just a few important considerations.
