I'm currently playing a Tabaxi Swashbuckler/Battlemaster (and I love it). I'm thinking of taking the Magic Initiate feat and thus gain access to the Find Familiar spell. I thought it would be funny to have a cat familiar and have my character think of it as a kind of miniature avatar of himself.
But even though that familiar technically would be a spirit and not an actual cat, I still had to ask myself whether it would make any sense for my character to think like that. I am hence looking for answers from official sourcebooks to the following question:
How closely are Tabaxi and ordinary cats related? Do they maybe have a special bond, or would they rather find each other a bit odd?
Even though Tabaxi clearly have feline characteristics, the rules notably do not mention any special relation to cats (for example proficiency in animal handling when dealing with cats), so maybe Tabaxi are no closer to cats than humans are to orang-utans?
