Hi I have cats too. Mine not a fan of THK. I was surprised. They eat everything lol. Since you have refrigerator and freezer issues maybe look at grain free can. There is a few out there that is good.

If *she like it more soupy try getting organic low sodium broth. I get mine at Trader Joes. Real good. Also watch cause she is older she might have some bathroom issues due to the change. Make sure you trim the hair on her whole bum. I had a Norweigian Forest Cat that passed last year so I so understand those issues. I also add in canned pumpkin in their diet if I am changing foods to give more fiber in their diet to help with problems. Good luck maybe post a pic. How big is she? They tend to be large kitties lol
