L4H here's some of the NV info for the
Instinct from their website
I included the dry matter conversion for calcium for you since Puddles needs lower level - though I'm not sure what the level she needs is but you can check lower end levels.
I didn't include the Vension variety cuz the phos level is

high
The levels below are per can
not converted into dry matter (except for the conversions I did

)
