A animal can be an Companion and a Familiar ?

[Atreyu00]

If a player has access to an animal companion and a familiar he can choose to have both as the same animal ?

No. Setting aside the fact that animal companions are at least small creatures and familiars are tiny, per their definitions in the CRB, putting familiar abilities onto an animal companion goes into bonkers territory.
