As much as he wants! 3-4 times a day would be best. His tummy is still tiny so he probably won't eat very much at once, after a while you'll get a feel for how much he can eat at one meal.
And how can I tell if my kitten is using the litter box I never see him but I have only had 3 accidents (only peeing accidents) and I don't see his mom stimulating him anymore and he is interested in the litterbox (hers we had one set up for him but it got in the way and he was more intressted in going in and out of hers). I also have found poop that would be about the size that he would poop out and there is more urin in it than usuall. Is that a good sign or no?
Well, the problem at this age is that their pee doesn't have an odor yet, and their poop isn't very stinky either. So if he's having accidents, you might not figure it out until he's older and smellier :/. I prefer to keep little kittens confined to a crate or small room when not supervised, that way I can keep an eye on their potty habits. But if he already has full run of the house, he might not like being confined now.
I guess you could potty train him like a puppy---take him to the litterbox after every meal, after naps, whenever you see him sniffing around, etc., and praise him and give him a treat when he uses the box.
I am almost always in my bedroom where him and his mom stay ( he is only aloud out if I walk out the door to get something and then I grab him and we walk back in the room I always have my eyes on him. And I always look to see what he is doing but I do find those types of things in the litterbox cause I always know when his mom goes cause I hear her scratching the box on the edge and on the top and I recover just to make sure I don't smell anything. So I know that the little tiny poops are his I'm more confused on how he learned when I havnt put him in there but he does watch his mom and how can I stop mom from eatting the kittens food cause she loves to eat the kitttens food and gets jelouse when he has food even though she has food right in her bowl
I officially seen him poop in the litterbox I had to put him in there cause he was about to on my bfs side of the bed and he is tired of that stuff happining. Buddy is alittle mad at me right now for whipping his butt and legs cause he got it on him. He scratched the heck out of me
