How can I adopt a cat considering my schedule keeps me out 9 hours per day?

I told myself I could get a cat once I found a job. Well, I’m on day two of work and I want a cat desperately! I have a lot of experience with cats – have had one almost consistently since age 6 with only a few short breaks in between.

Still, I’m wondering how I can get a cat or kitten then almost immediately leave them alone for several hours at a time while I go to work.

I know this is a silly question; many working people have cats! But it seems like it will be a difficult transition for the cat. How can I help reduce or, even better, eliminate sad/angry/bored feelings?
