We never knew mittens real age but we r assuming she is 14 weeks old about to be 15 on Tuesday. I would love to know her exact age and I am no cat expert and think she might be younger. Her eyes haven't turned her permanent color yet is that normal? U can see some green by her pupils. She also weights 3lbs and 4oz is that good for a 14 week old kitten? Here r some pictures please help me with this it would mean the world to me.
