Accidently mixed kibble

I accidently bought Nutrisca dog kibble and mixed it with I and Love and You cat kibble.   It was a 4 lb bag.  Will it be okay for my cats to eat it or should I throw it all out and start over?  My cats also get Fancy Feast wet once a day.

How much I and Love and You cat kibble is it mixed with? Same quantity, more, less? Can you get more I and Love and You cat kibble so the proportion of dog kibble is less?

The issue is, I believe, not that dog kibble is bad but rather that it doesn't have the taurine cats need. So if they are getting canned cat food and some cat kibble it might not be so bad.

If you do decide not to use it I wouldn't throw it out. Offer it to a cat rescue / TNR group who might be glad to get it.

I mixed the same quantity.  You made a good suggestion - don't know why I didn't think of that.  DUH.  I will donate my half bag of dog kibble and mix the remaining cat kibble in with this mix.  I think I will go buy another bag of cat kibble to dilute it even further.  Thanks so much for your response.
