Cats! (not the musical)

So lately I have been thinking I would like to get a cat. This could be for a couple reasons:

1. Our cat of more than 15 yrs recently died.
2. I feel a little lonely sometimes and think a puppy would be a little more work than I would like to take on right now. (Btw, I am not against dogs either.)
3. I see all of these pictures and funny stories about my friends and their cats and think "How fun!"

However, I feel hesitant to actually acquire my own cat for a few more reasons:

1. One day when I move out I would probably be taking this cat with me and would subsequently have to pay more for pets in an apartment and would be limited to those apartments that allow them.
2. I fear I could end up as a crazy cat lady. Just me and my ten cats for company! ;)
3. What if this is like a phase that will pass and then I end up with a cat and no longer have the desire to keep it. That's just unfair to the cat. 

So now I am left with a decision that I do not know how to make and will probably just continue to ignore and put off for as long as I can. If you can offer any advice to me, please do!

In the meantime, here are some inspiring cat pictures!
