I agree with all of the above responses. I don't think you're happy with Meka so there is no way she can be happy with you all. Love, patience, and understanding while the kitty grows up is what is required. Some cats stay playful and busy for years. Most of us are happy about that and find their antics unique and funny. You really need to start looking for her a new cat loving home. The longer you wait the harder it is going to be to find her a home. It is better to do it now before she gets too much older. Please do not return her to a kill shelter! With just a little effort on your part you should be able to find a no-kill rescue or a new home for her. Even if you have to drive out of your way I think you at least owe her that.
I honestly don't think this is ever going to work out and you really need to do something soon. In the future if you should ever want another cat then I really think you should consider only senior kitties. You need a cat that only needs a small amount of attention and generally sleeps the rest of the time. Actually I'm not sure you really want or need a cat at all.
Certain people with certain animals sometimes don't mix and I think that is the case here. It doesn't make you or Meka bad, it just means you are not meant to be together. Please find a good place for Meka.
