'Fraid to say, PP, that most domestic animals don't tend to share your soppy view of things! Generally if well fed and cared for they will forget their previous owner soon enough, although perhaps not their previous home as they have a homing instinct. Its all about survival.
We even experienced this with a dog...she was neglected so we used to "borrow" her for a year or two - walked her, topped up her food bowl, brought her in on cold nights (not in singapore obviously) and enjoyed a lot of affection back from her. Eventually the son of the person who owned her realised his dad was not really up to looking after her and took her in himself. A year later he brought her back to our neighbourhood - we were really excited to see her again, now sporting a very glossy coat, and went rushing up hoping for a positive reunion. She gave us a happy sort of look with a glimmer of recognition and then gazed her doting eyes up at her new owner. And so she should!
Cats, I should imagine, are even more fickle! You're just a convenient feeding and stroking machine. Their real life is what they get up to at night.
