Cats will learn from each other

A circumstance where the student taught the master... I rescued a stray female ready to have kittens. After all the kittens were in good homes, we kept the runt. Since we raised him indoors with lots of human interaction, he loves to be held, loves to play with water, and has no fear of humans. Consequentially, his mother will watch him and she´s learning. She is becoming more affectionate; she´s investigating water, and she does not run and hide everytime the door bell rings. She would have learned all these things naturally, but it would have taken years instead of months.
