Some great advice in there.
I only have one nutrition concern and that is the blurb about Vit C. Cats can produce all the Vit C they need, even those cats who are eating their natural diet of rodents/birds. Vit C can actually increase the acidity in the urine causing a formation of calcium oxalate stones and therefore I would hesitate to add any Vit C to a cat's diet unless under Vet care (or any other vitamins/minerals for that matter).
