Cats and chewing fake nails

Ive been curious to see if other peoples cats also do this.

I got fake nails recently and whenever me and my cat are cuddling, shell start grooming herself like usual and ill put my hand in front of her cause why not, she starts grooming me too. I noticed she likes to chew on my fake nails? Im not sure why. She didnt do it before, she did occasionally chew on my fingers but she specifically goes for my nails after i got them.

Why? Cat experts please tell me
