I understand many on here push and advocate for raw diet.. it sounds good but something I am unable to commit too at the present time.. I had a 10 year old male cat/neutered/indoor have surgery last fall to remove 3 large bladder stones that appeared to come from nowhere. I have previously only ever used Iams Original or Hairball formula and started him on Iams kitten.. So for 9.5 years I had absolutely no problems and in fact he has been the picture of health until now.. of course after consultation with vets and various health people the suggested the Science Diet food that costs a ridiculous amount 37 bucks for 10 lbs.. and of course it is only corn/plant products.. I am into my third bag now and have actually switched to mixing it with the Iams that I feed my barn cats because since the switch the amount of hairballs/vomit is ridiculous.. not to mention it appears that the food has no nutritional value as they eat a ton of it compared to the Iams which listed chicken as primary food .. does anyone have a decent and healthy dry food that I could look into? again I am not able to commit to a raw diet at this time but do not want to have a reoccurance of bladder stones again.. that was awful..I heard something about a food called Innova but can't seem to find it or know much about it.. I am limited for places too I have Petsmart and Tractor Supply as my main sources for pet foods..
