OK it's not with a cat, but one of my little pack goes frantic just as soon as she sees me pick up the keys for 'Millie', from then on she has some kind of sixth sense knowing when the sliding door is open, because then, just as soon as your back is turned she scoots off and can normally be found curled up in her bed!
She by the way is Bonnie, who was rescued by the amazing Spaniel Aid UK Charity from a traveller site. She was on the point of death when rescued, she was an ex breeding b*tch, she was still lactating, she had a truly massive grapefruit sized hernia hanging down to the floor, she was malnourished and was basically in a dangerously diabolical state. But after an 18 month battle to cure all of her many spinal problems and well in excess of £10k vet fees later she is now 100% fit and her entire life revolves around having fun and going away in our 'Millie'
