You have to be careful what you feed him. A lot of us here don't think much of prescription foods but this is one area where they have a leg up on non-prescription foods. They *are* very effective at controlling the crystals. I think I've heard of cats that have developed crystals while on a prescription diet to prevent them but generally they are effective.Originally Posted by SoxPD
the only thing is if the vet has said for him to be on the SD prescription diet would it be safe for me to change what he has? ive tried him on the SD wet food and he just does not like it but seems to eat the dry food fine.
You might be able to control the crystals with a non-prescription diet but it takes some effort to find the right foods. In general, what you want to do is some combination of : 1) feed foods that contain minimal amounts of the minerals that make up the crystals 2) feed foods that result in urine with an acidic pH so crystals can't form 3) maximize water intake to help keep the minerals suspended and flushed out rather than staying in the bladder long enough to coalesce into crystals.
My Jeta is prone to struvite crystals and I chose to deal with it by feeding her a raw food diet to keep her urine acidic enough to prevent the crystals.
You probably want to stick with the prescription food until you research what, if anything, else you want to try.
