bone broth

NEED HELP GUYS.

kitties been on bone broth for sometime, today I just made a connection that the bone broth could be the one causing her to have "feline acne" (her fur is dropping out from the mouth area) 

I notice that after a round of bone broth she would be grooming for very long..

is there a way i can make the broth less oily (made with chix bones).  or some advice?

Interesting question.  I don't have an answer for you on how to make it differently.  BUT, is there a reason why you feed it to her every day?  Any particular health issues?  Maybe you could try just giving it to her a little less often .  I keep it on my freezer is tiny containers to bring out once a week or so. (and I make mine out of beef bones, but it's still greasy)
