Is Orijin Regional Red too rich?

My two cats eat three wet meals a day (one at 6 a.m. one around 4 p.m and then at bedtime around 10 p.m.)  and one dry meal.  The canned food is all grain free, various brands, various proteins.   They get one 3 oz can split between the two cats at the morning and afternoon feeding and about 1/2 a 3 oz can split at the bedtime meal.  It doesn't matter what the brand or flavor...3 oz (1 1/2 oz per cat) is the maximum they'll eat at any meal.  The dry meal is 1/3 cup split between the two cats around 7 or 8 at night.  I've been using Wellness Core Turkey and Duck (fish and chicken free) and they both did really well on that.  I'd read so much about Orijin that I thought I might want to use that as a "back up" dry so I started mixing in a very,  small amount of Orijin Regional Red with the Wellness  (small meaning a 12 oz sample pack mixed in with about 2 1/2 pounds of the Wellness Core).  Immediately after eating this meal with the Orijin mixed in, one of my cats, BamBam, vomited everything back up....and then vomited a couple of more times over the next hour.  The other cat, Sammy,  was fine with it.    This has happened twice ---they've had the mixture for almost a week, so two out of 5 or 6 times.  I did notice last night when it happened, that the 1/3 cup seemed to have a little more of the darker Orijin than usual (not mixed as well I guess).  Does anyone think the Orijin Red could be too rich for him...or maybe one of the weird novel proteins like Wild Boar or Bison is a problem?  He does eat the dry food pretty fast so I think it  could also be that, except he never did it before I mixed in the Orijin.  He's wanted his bedtime meal both times and held that down fine....just vomits after the dry meal.   He was having some hairball problems and vomiting hairballs a couple of times a week, but I started him on the Vet's Best and have been using the Furminator and he's not throwing up hairballs anymore. 

It may be not only a bit rich, The Regional Red Orijen, but that your cat is eating the "new" kibble way too fast and it comes back up. He may also be sensitive to the first ingredient "Wild Boar". I guess, I would forego offering this to your cat for now and see if the vomiting subsides. If it continues, then you know there may be something more going on medically than food related. Orijen is an excellent choice though for a kibble. But, yes, very rich food.

I switched over from Orijen Cat and Kitten to the Red and both my boys are doing well on it. It's only about 10-15% of their diet though. They eat mostly home made raw and canned food.

I was giving my cat a teaspoon of Orijen Cat and Kitten after she finished her canned food 3 times a day. She would then barf 2 hours later. She loved Orijen, but she just wasn't digesting it well. I wrote Orijen and they suggested Acana since it is 70/30 protein. They thought the Orijen was too rich for her tummy. They did change the formula last year and a lot of cats have had problems adjusting.

They made the formula better though. Got rid of the potatoes in it.

Thanks for the replies.  I have been hand picking out the darker Orijin the last couple of days (not too difficult since it's only 1/3 cup of mixed food) and BamBam is eating the Wellness much slower and has not barfed at all.  I think he must have really liked the Orijin since he was eating so fast when it was mixed in, so maybe I'll see if using the Orijin as "treats" and only giving him a couple of pieces at a time will make a difference.
