Last summer I found a 12 week old kitten, Wally, at WalMart and brought him home. He is a very loveable and wonderful animal at times, but now that he is older and more familiar with his surroundings, he is becoming a holy terror. He will not leave my other cat, Sadie, alone, and is always picking fights with her even though she is twice his size and weight. He hogs all my attention and I cannot get a moment's peace and spend some quality Mommy-Sadie time with my first cat, who I can tell is extremely attention-starved. She looks at me like I've betrayed her and don't love her anymore. What's worse, Wally is most active at night and has a bad habit of tearing across the house, getting into things, knocking things over, and crying even though my bedroom door is open. He also won't let Sadie on the bed, and I miss having my fluffy footwarmer Sadie sleeping with me. I don't want to have to get rid of Wally. I keep telling myself it's because he's still a kitten, and a male one at that. He has been fixed, but that hasn't calmed him down at all. Will he eventually grow out of this reckless, annoying stage? I've had cats in the past that were rambunctious until they reached a year of age and finally settled down, but he is ten times worse than anything I've faced thusfar. I would really appreciate some advice so I can get back to my healthy relationship with my wonderful, perfect baby Sadie.
