If it is in them, they will accept cuddles in their own time. Play is good.

Jane was 5 months when I rescued her so she adapted fairly quick. Bob and Emily are adults and I have had them for 3 months tomorrow. Bob is learning to play and he started that first. My kittehs taught him to play. Now he does sleep with me on the bed sometimes and will get up on a low cat furniture for some scritches. He doesn't like to be approached for lovies and still doesn't like to be picked up. I'm working on it.

Emily will let you hold her for a minute, but then wants down. She sleeps on the pillow next to me. She does not like other cats. She's been 13 years on her own.

Keep on trying. y'all will get there.
