noah's mommy, all kidding aside, I have noticed that as cats mature their social habits, those associating with people, also change. That these changes are more pronounced with males more so than with females. I have few visitors here, but when they do come, it is necessary to watch which furkid does what to whom. Although my 2 major males (Snow Cat and Jumper) are currently being trained to be primarily house cats, their habits are also changing. Jumper starts yowling (at any hour of the day or night) and climbing things(like drapes), when he wants attention or if he is hungry. As of late Snow Cat is acting fearful -as though I am going to leave him, as he is now getting all excited when I return home from the grocery store. Also that he is becoming more vocal than before. And of course you all know about Tiger, how she has changed. It is assumed that their personality doesn't settle down until they are at least 2 years old. All of the furkids just mentioned are about 9 mos., to 1 year old.
