Thanks for the replies.
Cupofdog - what awesome information!
Ellie May - The nurse told me not to give Nutracal AT ALL. She said if she starts showing those signs bring her in, don't give her anything other than her food.
Nancy1999 - I am free feeding. I have for all my pets. I am aware that she needs protein with the Nutracal, she would eat her food about 5-10 mins after the Nutracal each time. It's like it made her feel better and she got her appetite back.
