Trying to get consistent information on what to feed animals from vets is like trying to get consistent information from lactation nurses. (I was one for part of my time as a nurse.)
We’ve tried everything in the world for our dog, finally hit on the right combinations, and she no longer has Shrek colored diarrhea.
Back to cats, those small parts that look like bone? I used to find salmon bones in some FF fish formulas. Our cat’s vet said not to worry; asked the vet here, she says not to let cats have it.
