Born feral brought home as young adult

Hello, I have a cat that was born around last August. He was born feral near my friends house that befriended the momma and kept momma and kittens safe from outdoor threats as best as she could without interfering too much. As the kittens got older they interacted with people more and I was chosen by my marz baby. Up until about 2 months ago he was a feral, outdoor cat that still had his momma and littermates. When we moved from my friends house we brought marz with us. He is now strictly an indoor cat (for his own safety) and not neutered (haven’t had the money yet)

he has started to excessively lick/suck on 2 certain blankets.he will lick/suck on these to blankets while purring loudly for 10-15 minutes straight. Is this normal given how he was brought up and his current age?

He will also meow constantly if not being given direct attention. He has food water clean litter box and plenty of toys that he doesn’t show much interest in. I am home all day and he has his own safe area from the dogs when they are out of their kennels. Is this also normal?
