I had a wild cat named Wild one when i was small she was gray and I ran around tring to get her to play with me but...she was not a playing cat. she hated people. she got in the house and had kittens behind the sofa and we didnt know it! she came up the vent had her kittens and she would sneek in and out from the vent. then kitten never made a sound! one day I was laying on the floor asleep and woke up in the middle of small baby kittens I thought God had droped them from heaven just for me to play with and love! Wild one wasnt happy but I sure was! there was ten on them!
I was 3 anyways none of then purred at all. I have noticed that if the moma cat has been taught not to do something the kitten wont either same with dogs. my dog wont bark in the house at all unless something is wrong.
if the moma cat was hurt and could not purr or was afaid to purr she could have taught your cat not to purr either. I tried in vain to get those kitten to purr just because I liked the fact they sounded like me with my asthma at night but they did it just cause it was a normal cat thing....
