Orijen Vs Life's Abundance vs Before Grain dry food

[Joey525]

Hi, I am a very excited first time cat owner. I am picking up my kitty soon and I asked my breeder what food I should buy. She told me she feeds her kittens purina one chow for dry & fancy feast wet. Ive been doing my research and I keep reading about those brands not being good healthy choices for cats and in long term end up being more expensive than high end food as you would need to feed more of the cheaper stuff to satisfy your cat. So Ive come up with 3 brands that seem to be most raved about.

Orijen
Life's Abundance
Before Grain

Does anyone here have tried these 3 or recommend one over the others?

I have ZERO concept of what would be best or how much a kitten or cat should be fed. I see that the prices of these are noticibly higher than most brands I see at petsmart. So If I buy somthing like a 15 lb bag, how long would that last for one kitten? Can somebody school me on how much exactly I am supposed to feed my kitten and how many x a day? I know there are directions on the back of the bags but I plan to serve with wet food so I am imagining I wouldnt need to serve as much. I was reading one brand of wet food that called for 2 3.5oz cans per every 6 lbs. So that would mean when my cat is 20lbs he will require 6-7 cans of wet food a day??? That sounds like A LOT of food for one kitty and expensive! I dont want to waste or overfeed my cat.

Which leads to my next question... is Fancy Feast a good choice to serve with high end dry food or would I be defeating the purpose? If not, can anyone recommend some fair priced better wet food choices?

Sorry so many questions. I just need to figure out a good healthy wet/dry combination and how much of it to feed. My head is spinning! I feel like a nervous new parent!
