Wow, that cat must have really trusted you, to turn to you in her hour of need.
My boyfriend's neighbour adopted a pregnant cat last summer. I helped looking after the cat and kittens when the neighbour was away over the weekend. They were an adorable mixed bunch - a tabby, a tabby with white, a black and white and a ginger one. I had my favourite (the tabby with white, that instantly sat on my foot as soon as it could stagger) and I kept telling everyone how happy I was, that all of them already had a good home, because otherwise I might be too tempted to take one. Guess which one didn't have a home after all and ended up at my place! It was destiny - he chose me, and I chose him and we just belong together.
