Yes it is, it was used very successfully by the breeder I got it from - however if you feel strongly about not using the egg or the egg white just omit as it is optional.
thanks...I was just curious. I am completely new to this whole kitten thing. My cat is pregnant now. She had 1 stillborn yesterday and nothing else since. I have an appointment for her to see the Doctor tomorrow. I was looking at recipes just in case they are needed. thanks again though
