I got a 4/5 month old kitten called Isis and she loves my hair shes jumps on my lap and stands up on her back legs and rest herself on my shoulder and hides her face in my hair, starts to claw my hair and she purrs. she prefers it when I hold her too and she even falls asleep sometimes, When I lie in bed she lies next to me or on me n claws my hair then aswell. I never had a cat do this so im wondering why she is doing it?
