I did this for bigwerewolf2019 at first it was cat and mouse but I decided for both of us to become big cats not a lion not a tiger or cheetah but a Black Panther next up is the Indominus Rex Transformation Audio

Two guys at home have got a serum to try out for both of them to become a big cat but they are becoming Panthers
