I had cats my whole adult life, and I loved them! They're so easy to care for, and if you want to go away for a weekend, you can. And they'll curl up on you or next to you, and they're such stress busters! Then when we lost our last one, my husband wanted a dog. I was nervous, but I love him so much! He's such fun, and he makes me laugh every day! But he IS a LOT more work, and I hate dealing with it on those days when my back is bothering me. But he gets me out walking WAY more than I would on my own, so it's all good! As for choosing??? I just couldn't !!!
