Hi all- I have a cat that my vet put on Royal Canin Selected Protein food due to skin allergies. I have 3 cats and cannot separate their food and we honestly just cannot afford to feed all of them this food. I honestly do not see alot of improvement with her skin plaques either. Is there a lower priced substitute someone would suggest? To be honest the cats do not do well with this food either.. they definitely do not find it appealing. Thanks!
