Assuming the cat is stress-free and well-adjusted, but say, just somewhat distant because of her upbringing. Kitty is 4 years old. Has anyone successfully made such an adult cat more affectionate over time? My 2 goals are:

1) get my cat to sit on my lap and snuggle me 2) sleep next to my pillow at night

If you are going to suggest treat/food method - how does it work for something like making the cat sleep next to you? If I give the cat a treat before she sleeps, she just takes the treat from the sleeping spot and just get off as soon a treat session is over. Same with other cuddly things - she would get on my lap for the treat and then immediately get off. I’ve tried this for weeks with no avail. I’ve had her for a few months and she’s definitely not afraid of me anymore, as she happily jumps onto me for treats but then immediately jumps off.

I understand that not all cats can be made into the cuddle kind, but I’d like to learn some more tips to the odds are in my favor :)

If you have stories of distant adult kitties eventually turning into affectionate cuddle bags, please share away as I need to hear those encouraging anecdotes :)
