Right now I have an ex-feral cat who doesn't like canned food, although I'm trying.
I never ever fed any of my many cats dry food. They all ate canned and none were ever fat.
If your cats like canned food, then that is a good option. I find it satisfies them more.
Right now I have a foster kitten - 4 months old - who is a PIG. I have to put her in lockdown when I feed the cats or she would eat everyone's food.
Maybe you could get your young cat used to eating separately. I find it works quite well for mine!
