So, to tag on to Lark's standard familiar post, again familiars are not actual living animals. Do not try to attract wolves to your home, wolves are wild animals.
The term familiar is short for familiar spirit, if you work with spirits then maybe one of them will agree to function as your familiar. If you don't, then you probably won't have a familiar unless you wanted to build a servitor to serve as one. That would be a magical construct, something like an energy golem, it would be limited by what you programed it to do but it might be helpful.
If you can astral project, you might meet something willing to act as your familiar in the astral. If you try this keep in mind that, much like humans, spirits can and will lie and will act in their best interests over yours. I would suggest taking the long way around and building a working relationship with a spirit before wanting it to be your familiar.
