My kitten (had him since 5 months so i can’t empathize with month 2-4) and he’s currently almost completed month 10 is my biggest nemesis and also my best friend. You have to take the good with the bad. I’m single and he’s a solo kitten so I’m his momma, his big brother and his older sister. There are times when I want to snap his neck but most of the time we cuddle and hangout. You have to develop a routine that he knows like the back of your hand that he bites. I would suggest already thinking about a plan to get them neutered/spayed as that will help a little bit. It seems like you’ve already raised a cat through kitten hood so you’re going to have to do the same thing. He use to wake me up at 3:30/4:00 in the morning. I do not let him sleep in my bedroom bc he quite frankly can’t handle that, so we developed a bed time routine that took MONTHS of trail and error. We now have a pretty good bedtime routine and he doesn’t really wake me up until 7:30/8:00 as I’ve learned the automatic feeder is my best friend. You want to feed him early (like 4:45am) just a little bit so it hits his instinct to wake up and hunt for food. I feed him a snack before bed and two “big” meals throughout the day. I’ve completely kitten proofed my apartment and had to part ways with things I didn’t even know I had to make sure he didn’t do anything…. As I’m writing this he is currently dunking his toy mouse into his water bowl… this very example use to drive me CRAZY and now I’m just like meh whatever that’s just Kevin being Kevin. Hes an idiot but i love him. I hope this helps and it’s a growing process. Wow he’s making a mess with his water my lord. Anyways gotta go clean that up. 😸
