Spending time with a pet can make everything seem better.
I know when I have a bad day, spending time with my cat eases my stress, helps me put things into perspective and just plain makes me feel better. There's nothing like cuddling with a cat and having him or her purr their contentment, telling you they are enjoying the quiet time with you as much as you are enjoying the quiet time with them.
So if you have a pet, be sure to spend quality time with it every day. It benefits both of you in so many ways.
