the vet said that was what did it; he trusted me
Animals definitely learn to trust. I rescued a kitten who'd been found on a muddy driveway in the freezing cold and with a tail that had been broken. She learned to trust me so that, when was pregnant and ready to give birth, she waited until I got home from work to have it and wanted me to help her. Once she was back to her old self, (the baby's eyes were barely open), she would pick it up in her mouth, drop in in my lap, then run off to play with my other cat, knowing I could be trusted to babysit. Otherwise, she was with her little one all the time.
