Out of food!

Hi folks, 

apologies on the nature of this post. I'm running a bit late here but I noticed I'm almost out of food for my cat. Unfortunately a cold front/snow blows in here starting tonight and, since I travel by bike, if I'm picking up food for the month I should do it today while I'm out. 

So here's some quick information to see if you can help me make a decision:

My cat has been on raw for a little over a year. Primarily fed her K9s Feline Natural chicken and lamb freeze dried, but the new store doesn't carry this. For the past month I've fed her bison from Carnivora, which is really well priced and she loves bison/red meats. Carnivora has quite a bit of bone in it, however, since it's also blended for dogs. 

I have to decide if I'm going to pick up another package of carnivora bison, or try another food. Whatever I get today is what she's stuck with for the month. 

Should I play it safe and get more bison/elk? Carnivora also has other proteins that are cheaper, whereby I could potentially get more (ie duck, rabbit, chicken): http://www.carnivora.ca/html/featured_products/index.cfm

But they also have Primal available, which from what I understand is more popular down in the United States (we're up here in Canada). Any experience on that? Also a bit high on bone?

Thanks for any advice!

If you're concerned with bone content, you can substitute a small portion of your meals with cooked egg whites and raw egg yolk... It's not something I'd do for a long term (unless you have a CKD kitty), but it might be okay for a short while.  The egg whites will provide protein, but might curve down the calcium/magnesium/phosphorus of the bone. 

If you don't want to do that, then maybe just adding the egg yolk by itself.  The yolk will provide extra biotin and fatty chains to help keep things moving.  Careful though... a little bit goes a long way.  I usually keep some yolk in a small container, and use just a spoonful at a time.

Hi, thanks for the reply.
To follow up, I bought some Carnivora turkey. But she wasn't crazy about it and it often was left out then thrown out. Similar to how she reacts to eggs, unfortunately

A few days ago I grabbed some elk and beef offal. I was mixing the offal with the turkey to try and get her to eat it better. She mostly ate around the turkey and has wound up eating offal for almost three days now.

Earlier she threw up quite violently, but I couldn't find any evident chunks in it to point out the problem. It was mostly bile. About an hour later, she threw up again. Ten minutes ago, again. She seems to sleep, throw up. Currently is curled up on my lap on the floor in the hallway while I wrote this from my phone.

What are my concerns here?
Could the turkey or offal have been bad? Perhaps a food allergy to the newly introduced beef offal? Too much offal at a time? Maybe salmonella poisoning?

I'm going to throw out the food in the fridge, give her bowl a very big cleaning, then maybe give her nothing to eat for the night. If she seems okay I have some cans of friskies chicken I can try instead, or dethaw an elk patty, but I wanted to get an opinion here.

What do you think?

Have you taken her to a vet?  Vomiting that often is usually a sign of a medical issue, not necessarily food related.

Take her to a vet as soon as possible. If she isn't keeping food down she is at risk for liver problems. That can quickly be fatal.
