Hello,
As a general disclaimer, my theriotype is wolf so my writing will be a little biased, but you can obviously apply this knowledge to other theriotypes as it applies for you.
One of the noticeable parts of therianthropy is that we therians "inherit" some of the needs of our animal theriotypes. What traits are "inherited" in this way depends on the theriotype obviously, as well as on the person. While some people may very intensely experience an animal need, others with the same theriotype may not.
So, certainly it is not required if you are a wolf therian that you have every single need that the wolf has. It's just something that applies to certain people. For example, I experience a strong need for hierarchy within my friend group (kind of like how it is in wolves or sled dogs), but many other people who are also wolf and dog therians do not experience this at all.
Many therians have theriotypes which are forest animals, so there are obvious needs like for example... deriving a sense of comfort and security, from something like this:
Of course even plain humans who are not therian at all, feel attached to an environment that shows sun, fresh water and signs of life, because this (surprise) is where humans can naturally live. But a forest animal might feel something more, like a need to sniff around or get the sense of layout of the woods. These are things that you cannot really get from a picture on the Internet, you have to go to the woods and experience it yourself.
A wild animal in it's natural environment would be guided by impulses that lead it to it's next meal and the experience for therians is not much different. Even though we don't have a need to hunt, etc, we might derive joy from doing things that we feel driven to do.
I imagine something similar applies no matter what your theriotype's natural environment is...
Disclaimer: Please be cautious, alert and familiarise yourself with what humans need to stay safe in your wild environment of choice. Regardless of your therianthropy, you are a human and you have human needs and limitations. Wild prey animals can defend themselves and can incapacitate you, and it is completely possible to slip, fall and hurt yourself (I speak from experience!), etc, so be sure to keep a lid on your drift through the animal mindset and keep your human ass safe!
Many therians experience social needs of their theriotypes to some degree. It may well be one of the reasons that wolves are so present in the community, because many of us feel the need to stay close with some kind of friend group on a daily basis.
But this is not something that we intentionally, purposefully do. It just sort-of turns out that way.
Feel free to add comment and describe some of the animal needs you experience in replies.
LP,
Dusty
