Take for example Faith and Lillibet. Lillibet acts like a little kitten and will snuggle into her Mum, making little noises, but really she is being sneaky and Faith falls for it every time. Lillibet then, still making tiny noises in her throat offers up her neck for washing and Faith immediately obliges with purrs and washes. What is really going on is a space war. Usually, Faith has the best spot next to Momma and Lillibet wants it. So once your soft throat has been offered for washing and your Mother obliges and you lull her into a false sense of security, it is time to make space. Lillibet strikes out at Faith, pushing her off with her paws and holding Faith 'at paws length'. Sometimes it's hard to imagine who is the Daughter and who is the Mother? But push and wait she does and wait and wait until Faith gives in and backs off a few inches and Lillibet can snuggle that bit closer to Momma. But Faith, not one for giving up her space easily does not back off entirely or leave the comfort of Momma's sid, she sticks there like a little limpet, leaning in harder and harder until eventually Lillibet and her big bottom are laying right on top of her Mother and and in turn they are heating Momma up too.
Who will break first? Who will give up their space? It's anyone's guess.
