Stone Diet

Question
6 year old female spayed.  Vet tested, found crystals in urine, recommended Hills Science diet for stones.  Is this a good choice.  Working on behavior modification, positive reinforcement with "yummy" treats...is cooked chicken or liver ok given her health condition?  Please advise, thank you in advance.

Answer
Yes, I would go with your vet's choice of diet.  Those that might criticize it have nothing to back up their ideas but speculation and junk science.  

Treats don't have to big.  Some people use Cheerios.  the regular kibble often is fine.  If you do use chicken or liver, make the pieces very small.
