Well it is really just your decision if and when you want a familiar, it can be a physical animal which would need to be taken care of and such or it can be a spiritual animal though some people say that your familiar would choose you and not the other way around but you can try looking for your familiar so don't start thinking that you are not capable of having a familiar you just never know

Familiars are not physical creatures, they are spirits that Aid a Witch in their practice, generally they appear in animal 'form' which is part of what lead to the legends of Witches having a pet that would fly around the town at night, harming innocent villagers and drinking blood to feed a Witch and all kinds of fun things.
Familiars can be 'obtained' in a variety of ways - I may make a post on this in the future.
Coven Given - as in your Coven or Gathering would give you access too a group familiar or would help you obtain one when you're ready.
Born With - This more falls under Fetches, which is another kind of personal spirit of a Witch, essentially the same thing with a few distinct differences. Essentially when you're born, the Familiar is born with you.
'Summoned' - you can reach out to the Otherside for a spirit to form a working relationship with.
They find you - They will turn up, almost out of the blue and pretty much go 'I want to work with you'.
Just because you want a Familiar doesn't mean you'll ever get one, some Witches never have a familiar in their life, some have more than one, it's just how it is.
