[WH40k] I want to open a animal fighting pit. Is this legal and does it break any heresy laws?

Not only is it legal, it's very popular.

In one of the Ravenor novels (I think), they infiltrate a giant gladiator arena/circus/animal fighting pit called the Carnivora, where all sorts of exotic creatures from across the galaxy are displayed/fought/eaten

Now, in order to procure all sorts of exotic predators, you'll likely have to deal with Rogue Traders and all sorts of other unsavory characters who dwell on the fringes of the Imperium, even Xenos. That is where it gets complicated.
