Congrats on the pair of you "getting" each other! Post pics if you can!
I've attached a link to a site that I love and recommend. It is a non-biased rating site for food. Check out brands you wish to feed or as suggested, search for 4-5 star foods.
Many of the higher rated foods need to be sourced online or at independent or natural pet stores yet places such as Tractor Supply and chain pet stores will carry a few.
Restoring her health will be the best way to ensure that you have each other even longer!
