Note: This is my first real attempt at a mod. Any help/advice/tips are welcome.

It has always bothered me that wolves and bears are so bloodthirsty that they will jump out and bite your leg off. . .when you're just trying to pass them by and minding your own business. In real life - this doesn't happen. They're likely to run first, attack later.  There was an old mod for Skyrim that took care of this, and another for bears. But those do not work in SE. So - I decided to try tackling the issue myself. And. . .I do believe I got it to work. Yay! Rather than having an esp for each animal, I decided to combine them into one, since the problem is nearly identical for both bears AND wolves.

So, this makes bears, wolves, sabrecats and crabs *less* hostile and more 'realistic' - well, within the confines of the game, anyway. They are still dangerous. Don't go up and try to hug them. But - if you happen to like to hunt them, you can still do so without feeling *TOO* guilty. However, now they will start to warn you when you are a LOT closer, and won't actually attack until you're in their personal space. (Like I said. . .no hugging! No handshakes!)

* Bears are bolder and will attack after warning you a few times.  Bears. . .well bears can be grumpy, so don't test them!
* Wolves are a little more tolerant and give you more time to get OUT of their face before they'll attack. They take a bit longer than before they get mad and start to chew on you.  
* Sabrecats also will give you some time. Like the bears, they will warn you before attacking, and give you time to back off and get out of their 'space'. Their range is a bit 'longer' than bears - they'll warn you sooner, but you should have plenty of time to get out of their area, or just keep going when you see one.
* Mudcrabs are no longer hostile. Cause no one wants a rock to suddenly sprout pincers!
* Elk have been tweaked to make them a little less freaked out, while still moving away. (Under testing. Previous behaviour was causing random deer/elk to go hostile for no apparent reason. Trying again!)
*Horkers are non-hostile. (Because they were hostile. . .why?)

I decided to keep predators on the dangerous side because. . .well, they are wild animals and predators. The old mod that I got this idea of had wolves running when they saw you - and that was REALLY annoying if you WANTED (or needed) to hunt them. This way - you have the option. Keep going - or hunt.

This should not effect 'special' animals at all. Just the basic wildlife. Quest animals/spirit animals/alpha wolves I left out of this so it shouldn't interfere with their behaviour.

*Note: In my own playthroughs, I have found if you run into a *pack* of wolves, they may still aggro on you seemingly quickly. This seems to be due to entering wolf1's aggro range and not exiting it fast enough before you clear the pack. (or wolf2 or 3 tripping you up and slowing you down so you *can't* walk away fast enough! :D)  Trigger wolf1 and by the time you pass wolf3, wolf1 is going aggressive - which sets the whole pack on you. I've thought about tweaking this - but I actually like how they pack up and it's a little unpredictable whether they'll 'set each other off'  or whether I can run right through them. To me, it keeps the danger of the wild creature - while still removing the frustration of the constant attacks.

UPDATED:

1.3 - April 15, 2017
- Finished tweaking elk and deer. They're probably as good as they're going to get. Seem to flip between being shy and bold, sometimes they let you get closer than other times.
- Added Slaughterfish by request. No longer hostile. Still brave if attacked.
- Player Horses are no longer randomly targetted by predators. Spriggans still may attack. Spriggans are not nice. ;)

1.2
      - Removed the accidental dependency on the Unnofficial Skyrim Patch. Should no longer be required to use mod. (Though still is recommended!)
      - Added Horkers - No longer hostile. Realistically sea lions, walruses generally *are* territorial, but Horkers really serve no purpose being hostile - except being annoying. They're too slow to be any real threat - and as much as they are hunted, even these creatures would have learned some caution.
      - Fixed Mudcrabs. Non-Hostile.
      - Tweaked Elk (again). They were showing some tendency to randomly go hostile for no apparent reason. Semi-realistic, but still annoying.
      - Tweaked the aggro range on Spriggans. While not technically wildlife, they do affect local wildlife and had LONG ranges. Should give the player a bit more time to decide whether to clear out or deal with the spriggan and its companions.

1.1
      - Changed the name of the mod to include more animals
      - Tweaked bears and wolves so bears and wolves will no longer 'gang up' on players together. Wolves will still 'pack up' with other wolves, but you should not find yourself fighting a bear and 3 wolves all at the same time. (Unless, of course, you managed to tick off a bear at the same time!)
      - Added Sabrecats to the mix. Still aggressive, but more cautious and less 'stupid'. Still may 'pack up' with other Sabrecats in the area once riled up.
      - Added mudcrabs to the mix. Non-hostile unless provoked.
      - Tweaked Elk/moose behaviours so they freak out a little less quickly.

Compatibility: Pretty much anything that does not edit the behaviours of these animals, I'd imagine.
 *SkyTEST is the only mod I'm currently aware of that may conflict. May or may not be compatible. I don't use SkyTEST) myself, so if someone feels like testing it, please let me know! It's also possible that if you like Skytest and load it first, then this mod after it that it'll give you the benefit of both? Maybe?

Polite feedback is welcome.
