my 5 month old spayed female lop seems cross with me. When I’m sitting on sofa reading or watching telly she climbs on my chest looks at me then digs my T-shirt and chews it. I move her off then she comes back seconds later she also bites my arms or skin now and then but not hard enough to draw blood but hard enough make me jump. She has a friend he follows her everywhere they lay together groom each other she will dominate him if she is worried he will get more food than her but that’s the only time I see her cross with him. She bites at me if I have to pick her up but she is coming to me I am not forcing her to stay in fact I push her away. Any ideas?
