Cat on whole prey throwing up
I started to put my cat on whole prey about a week ago. She went from eating mainly ground raw with some bits and pieces of real meat and organs, into whole prey, so not a crazy transition.
At first it took some coaxing to get her to eat the full animals, but she's at a point right now where she's eating them and enjoying them with no encouragement. She especially loves the chicks.
However, one thing that's been happening is that she's been throwing up on a regular basis. She had diahrrea once, on one of the first days, but since then her stool has been fine. Only a couple of times she threw up the actual food. Now what's happening is, she only throws up hairballs. The hairballs consist mostly of mice hair, plus some of her hair. Before that, it was very rare that she would throw up hairballs.
She's not regurgitating the chick feathers, only the mice hair. So what I started doing as of yesterday is feeding her just the chicks, and the hairless pinkie mice, as well as some ground food she used to eat before, for variety. I'm trying to see if she will continue to throw up if I'm not giving her the mice or rats that have hair.
Is it normal for cats to regurgitate the fur of their prey? Do cats in the wild regularly throw up? Or is she just not used to it?
