Hi akbah's mum,
Thanks for asking. I immediately upon diagnosis and reading/self-educating switched Terra to canned. She ate it at first and I thought I was blessed with a cooperative cat. But that was short lived. She has been making me crazy with her finickyness and so two days ago she just refused to eat the canned. In desperation I gave her dry Iams - high carb and her old food - rather than have her fasting. Now she's coming around to eating the canned again. At first I just got a bunche of the different low carb foods, including Fancy Feast, which she ate wholeheartdly for a while and then turned her nose up at. I again read Binky's list and some other articles and have narrowed it down to the several canned foods which are okay enough low carb but also are low phosphorus. And from that small number, I find she's willing to eat one: Wellness, which also meets my standards for good quality meat. I am steering away from low carb dry food because it's also very high in phosphorus and I suspect that she has some kidney problems. Not sure but wanting to be on the safe side w/o a diagnosis, only observation.
Lots to learn. I feel as if I'm behaving obsessively for the last month. My friends are looking at me strangely for all the time and effort I'm putting in here.
