A Cat-astrophic Transmeowgration?!

A boy dies but fails to recall, barely any traces would surface. But those traces make up his mental psyche. He knows he was human. Yes, he remembers he was old enough to read comics, manga, webtoons and Xianxia. Old enough to play games and hang out with family and friends. Old enough to...KNOW! He was NOT...FLUFFY! So why does his body feel so...weird?! Though he does not recall his death, his eyes open at last. He awakens into a beautiful fantasy world with gorgeous mana, flowing throughout the air he breathes. Dwarves, Orcs, Elves and humans - ohh! That elf summoned a spirit! That guy over there became a werewolf! So other races exist! No wonder his body feels strange! - 'Co-Could this be...an ISEKAI?! Perhaps...this is finally my chance to live as the fantasy protagonist of my dreams?!' - "Me-Meow...MEOW!?! Meow...meow meow?!" ...what...?
