"the collars belonging to the cats" -- there are multiple collars, and multiple cats. the way to represent this is "the cats' collars." you add the apostrophe to the cats, because the multiple cats own the collars.
"the notebooks belonging to Janet" -- here, you have multiple notebooks, but only one janet. the way to show this is "Janet's notebooks." the possessive s is added to janet's name to show that the notebooks are hers. the possessive s or apostrophe would not apply to notebooks, because the notebooks don't own anything. only janet owns something.
