Is there a feat that changes Wizards Familiar to an Animal Companion? I'm sure I've seen such a feat

I think I saw a feat that changes Wizards familiar to Animal Companion along time ago, but I can't remember if I'm thinking right or just making up random feats in my head.

I remember a prestige class that did that back in 3.5. It was called the arcane hierophant and was found in Races of the Wild but I can't remember a feat that did the same thing.

I think it may have actually turned your animal companion into a familiar and allowed you to benefit from it being both... it's been a while so I'm probably way off.

Back in 3.5 there was a class variant in unearthed arcana that swapped the familiar for an animal companion as a druid of 1/2 level.

If you're looking for something that's purely Pathfinder, the answer is there isn't one.

There is however a sorcerer wildbloodline that allows for a druid style animal companion, the Sylvan one. To get it as a non sorcerer though you have to spend three feats and wait until you're in your upper mid levels. Four if you want it to be at your level.
