Is there supposed to be blood in the raw food?

Is it ok, I mean I never read about the bloody part & it's kinda grossing me out. I'm giving them OC Rawdog Rabbit for dinner only & they absolutely LOVE it & are doing fantastic on it. They've had Nature's Variety, Primal & other premade raw food & I never noticed blood in them?
The place I got it from ordered the wrong size for me, I wanted the big package of medallions, but got me the smaller tub instead. I had to defrost the whole tub & section them into plastic baggies & refreeze them. It has what looks like bloody juices...when it's defrosted again.

loll
