If you’re not feeding your cat moist food every morning that would eliminate the crystals it has nothing to do with the dry food at all. Most cats that get crystals are males so if your cat is a male then that would be the cause. I’m not well aware of female cats getting crystals because I’ve only had male cats.

I wish I had read this sooner. Both of my cats are very ill with kidney failure after a few days of this food. I don’t know if they are going to survive, they’ve been in the hospital for two days on IV.

Hello Lucy, apologies for the late reply! The Performatrin Ultra line seems to offer the widest variety and is marketed as “functional, whole food”, though that doesn’t mean much. The Performatrin Naturals line is marketed as a “natural” product, but a look at the ingredient list shows that it’s really not any more “natural” than food from the Ultra line and seems to rely heavily on sources of plant protein. As for the regular Performatrin line, this has been rebranded as Performatrin Prime, so the two are one and the same. These foods are supposed to focus on life stages and specific needs.

I see; thank you for explaining. I can’t make any assumptions or claims about what happened, but it does sound very troubling. Thanks for sharing your experience.

Thank you, I appreciate that, however She always drank that much from when we got her at 2.5 months old and she passed at 7 yrs with no hint of a problem in that time.

Drinking 2-3 cups of water a day is a huge amount, and excessive drinking is a symptom of kidney disease, so I would suspect that your cat was sick without you noticing—kidney disease can advance quickly. My condolences.

not true – it does not matter how much water they normally drink, our cat drank probably 2-3 cups of water on her own in a day, died of Kidney Failure after being fed your cat food. the food was the only change and it came on so sudden when there had been nothing wrong with her before.

I wish I had looked at the reviews for this food last week before I fed it to our cats and seemingly killed one by doing so. She got sick on Monday night (after I fed them this food for the first time because we had run out of the regular food we feed them) She passed away on Friday evening from Kidney Failure, the only change at our house was this food. I agree with you that this should come with a warning.
