Pubert is older and doing amazing on Orijen cat. He was on medical for a LONG time, and then got sick, after tests and more tests we found nothing. he had lost weight and was puking twice a day. We switched him to Orijen, his coat is the softest it's even been, it's cheaper then medical at only 1/4 cup per day - he eats less per day, he waits for his food now, and he put on weight.
The best part - he only pukes once in a while. (why do cats puke for no reason? geesh!)
I also give him Evo wet once a day with his kibble.
