The main thing is to keep an eye on her poo though. 
I have Phoebe on the RC also, but I've had to use "mix-it" canned, just a spoonful mixed with warm water and the RC and she eats it all up right away. If I only give her dry food she won't eat it. 30 minutes after she eats I take her out and she poo's and pee's and all is well. I hope this helps..
