Gracesmum, your Grace sounds like our cat. Mia absolutely adores my husband, fawning over him as soon as he sits down, gazing adoringly up at him, waiting to be petted and stroked. Me? The one who does everything for her, and gets treated like something she has to wipe off her feet!
I had a cat once who was a one-woman cat. I went on holiday leaving my cook to feed him (to be clear, this was in Africa) but he went and stayed in a colleague's roof and refused to come down until I came home and called him whereupon he almost flew down and galloped over to my house, calling out to me all the way. I suspect he had a small proportion of Siamese in him. He was certainly unique.
My dog was absolutely loyal and totally committed to me – hardly surprising as I gave him a secure home after he had had four different owners and three different names by the age of seven months. My cats are a bunch of tarts and a loyal only insofar as their meals are served regularly. Oh, they let me stroke them sometimes.
Grace, I fear, is totally fickle. Who feeds her, walks her, gets up in the middle of the night to her, wrestles with her at the vets', worries about her, clears up after her and generally is 100% dog focused? OK you've guessed, me. Whom does she adore with a passion, gaze at adoringly, welcome with canine hysterics when he has been out without her? That's right DH. So I may be my dog's "best" person, but not alas, her favourite one
