Not really sure what is causing the crystals. Raymond and I eat a raw diet that our Mom makes for us each week. The recipe is from the book "Natural Health" by Dr Richard Pitcairn.
My Moms think that they need to add some Vitamin C to our food. It's optional in the recipe, and they are kicking themselves for not adding it all this time. Vitamin C would help keep the crystals from forming because it would keep my pee more acidic.
If any of you cats have any advice for us, please leave us a comment. We don't want to stop eating our raw food. It has made Raymond's itchy skin go away, and except for the crystals, we are both very healthy cats. Mom went out yesterday and found Vitamin C that is in capsules and will be easy to mix into our food.
