Sophia will only eat the FF that I have given her for her diabetes/she is diet controlled. She also has hyper-t and now it turns out that she has kidney failure too. The vet gave me a few samples for kidney food but she hates every single one and I think it is better to have her eat something so I keep feeding her FF which can't be good for her kidneys. I would like to give her half FF and half of a good kidney food. Can somebody help? Thank you.
