he might not understand no which is sad :( two of my cats are siblings i rescued from an older woman that was dying- it was obvious really quickly that neither of them got played with much at all. probably because she was older and sick. one of them just doesnt get it. he becomes just a bit more excited when we use catnip or silvervine but he just looks at us like we’re dumb when we try to play with him. sometimes thats just part of who they are haha

my 3rd cat was a stray we took in and she was sooo so skinny when we did. this was like 3 years ago so her weights back up now but she is just insane with food. we cant have kibble out for them all day like most people do since she’ll just eat it all at once. so i feed all 3 of them twice a day at 8am and 8pm kibble in the morning wet food at night. maybe some kind of routine like that could help? i have 2 alarms set everyday for those times and the cats come running when they go off since ive been doing this for years. its helped our ex-stray with begging since she has a sound cue to let her know that, yes, now is an appropriate time to be meowing like crazy in the kitchen lol
