Congrats on the new kitty :) I have 2 cats. One was 6 when I adopted a 4 month old kitten into the family. I was hoping that they would become best buddies (both females) and have each other for company when I was working 13 hour shifts. However, 6 years later, they just tolerate each other. The youngest is very attached to me and freaks out when she can't see me. The only time she sleeps soundly is when I'm in bed and she's pasted up against me. The rest of the time she sleeps with one eye open, peeking at me to make sure I haven't gone anywhere. If I get up to go into another room, even if only for 2 minutes, she's right behind me. And they are so jealous of each other. I can't pet one without the other demanding equal attention.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
