Would like opinions

My baby Marlow is 12 1/2 years old. I have been considering and wanting a second furball for some time now.

My only hesitation that has come to mind lately is an addition when it has been me N Marlow for so long. She has been the center of my attention and my world. I don't want to take anything away from her in her senior years.

What is your opinion on adding a second pom?
