<human>: Can you give me the gist of the text in a nutshell?

Hi r/cats

I've had this cat (Nova) for about 6 months now, i got her from the RSPCA when she was approximately 6 months old (the RSPCA said 2 years old, but she has grown so much and changed so much since then that it's hard to believe she was an adult cat in the beginning). Nova is a wonderful cat, she never scratches even when i'm trying to play with her, she is docile and friendly with guests, and is just a nice animal to have around.

I am just confused by her lack of affection towards people and her general attitude as well.  I believe she has some sort of OCD where closed doors are not allowed in the house, because when doors are closed, she scratches at them until they are open, even when she has no desire to be in that room.  I try and play with her at least a couple of times a day, but she just doesn't seem interested, and she just hides under a bed or cupboard while i flash some string around.  She also has never even attempted to jump on my lap while i'm sitting, or on my computer or anything. I know it's annoying when a cat jumps on your keyboard as you are doing something, but it's pretty much worse when your pet refused to of anything of the sort.

Now that's not to say Nova doesn't like me, everytime I come home from work, she greets me at the door meowing and pouring and wanting neck scratches, but throughout the rest of the day, she just lies in same room as me, not seemingly wanting anything but a pat every now and then.  She will often be in the same room as me, but never will try and sit on me or anything (besides scratch my chair, which i then pat her when she does).

I've had 5 cats growing up, and none were even remotely like this.  They all were clamouring to sit on your lap and just... I don't know, be like a normal cat.

Am I doing something wrong?  I feel like i have a strong connection with Nova and I love her more than anything, but it's just such a different experience than anything i've had.

Has anyone else had similar experiences or anyone have any advice?

Thanks
<bot>: My cat never wants to sit on my lap, or play around with string or toys I get for her.  Is this normal?
