Lost a fic keep mixing details with a different one

So I'm looking for a fic that i put down to wait for it to finish(tryna see if it is but wanna re-read it anyway) but keep mixing it's details with "SNAKES ARE VERY NICE" by Oulixeus

Main details are Harry gets/is planned to get seven familiars 5 are snakes one is his owl(don't remember if it's Hedwig or a different one) and one is a Kneazle he gets from figg

Each familiar has distinct personalities and magical ability to balance Harry. He's also moderately op from what I remember. Help greatly appreciated
