Get a second cat. 2 cats, 1/2 as much work,
I fear that is not true. I have a chronic illness which means I have bouts of extremely low energy or complete exhaustion. Then there are days which I work doubles and need all the rest and sleep I can get before getting up at an ungodly hour to work another double the next day. I
barely have the energy to take care of
myself. One morning, I realized I had been so exhausted the night before, I collapsed and forgot to feed her night portion. She's young and polite enough to wait for when ever I feed her and didn't nudge me or meow to feed her. (We have no set feeding schedule as my work hours are so different each day/week.)
I have had the hardest time with just one cat.

I KNEW better than to get a kitten. I was originally planning on getting an older cat, since I had cats before. But when the cat distribution network gives you a cat, sometimes you do not have a choice.

I hoped I'd be able to handle all her energy. Many shelters here will not even adopt out young cats under 3 years old, unless they are in pairs. But, I didn't like any of the other kittens when I found this one. And this particular shelter didn't have that rule.
I was planning on getting her a companion within the next few months. But with her so active and into EVERYTHING, I have actually thought of taking her back to the shelter as she is sometimes too much for me at this point in my life with my illness. (They ask everyone to give them the first chance to take the cats back if we can't keep them for any reason. They are a no-kill shelter.) It's actually not fair to her, as she NEEDS to play. She is young and could use another cat her age to play with and grow together with.
Yet, I fear getting her a companion will be way too much work. Someone once said, "Having two cats is actually twice the mayhem," and I think he's right. Every step of the way, I've had to teach this one cat what is acceptable behavior, to learn certain commands and tricks, what not to get into. What I need to remove or move as she will get into it anyway.
The idea of bringing in a second cat, whom I also have to spend time "training", after this first cat finally somewhat knows what to stay away from, just seems too much work. And the new cat may un-train what this cat currently knows not to do if she sees the other cat getting into stuff. Getting a second, much older cat may be better for
me, but may not be much of a companion for her, if the cat is too old to play with her.
