On the Hunt

You have so many 1 drops with the beast tag to choose from; Second spring paw, Alley Cat, Dire Mole, etc.

Stitched Tracker

It's your only non-beast, so you can probably just cut them for Master's Call.

Bear Trap, Freezing Trap, Explosive Trap

Bear Trap is on the weaker side of things, and I find Snipe to be generally disappointing. Wandering monster is just generally more effective than bear trap, Cat Trick and Pressure Plate are both secrets you might also want to consider.

Grievous Bite, Hunting Mastiff, Explosive Shot

Your list is pretty aggressive with double Toxic Reinforcements and Vicious Fledgling, good replacements for these would be Fresh Scent since you're an all-beasts deck or maybe Phase Stalkers to lean into the secrets you're running. A weapon like Headhunter's Hatchet or Eaglehorn Bow wouldn't look out of place either.
