My cat is almost 15 and has kidney disease for less than one year. Next blood work next month. Having so much trouble finding a kidney food she will eat long term. Have some wet she'll eat here and there but my cats are used to dry. We have tried 3. The last one, pro plan which her sister eats in regular and she used to eat was great for awhile but now she tries to steal the other cats regular food. Anything that's worked for your kidney cat with other cats in the house, please. Thank you
