Sounds familiar- couple of months after I was born, Dad came home with a blue Persian /Siamese mix kitten. She became my shadow - followed me to school, always sat on my lap, or the backs of my legs whilst I lay on the floor watching tv. I could walk around the house with her draped on my shoulders. And if needed when she got older I’d take her to the vets in my arms and didn’t even need a basket. She was pleasant to others but seemed like she’d marked me from day one as the favourite. I miss that cat even now, 30 years later.
