Magnesium level of food.

Species: Cat
Breed: ASH
Age: 2-5 years
I have two cats. Casper has urinary tract issues. He is currently on a .085% magnesium cat food. However that particular cat food is being discontinued. I have found a another cat food I like the magnesium level is .01%. Is that too low of a level for him? And is it too low of a level for the normal cat?


Online vet, Dr. Marie

Dr. Marie replied:

We actually don't worry about magnesium and ash levels any more. Back 10-15 years ago this was what we thought was important for cat foods, but there are many more factors to consider.

The most important thing is something called RSS - relative supersaturation. Unfortunately you will only find foods with good RSS levels sold in vet clinics.

If I have a patient with a history of urinary tract issues I always recommend them to stay on a food like Royal Canin s/o or Hill's c/d.

If your vet says it's ok then you can try going to a high quality food like Iams or Science Diet and this is ok for most cats.
