Cat model appearing as having human skin

I've just started with Mcreator today and everything fine until I tried to create my own mob. I went to novaskin and edited a cat skin and put that as the texture of the entity and based the entity model on ocelot (since there's no option for cat). I tried the mod but the cat kept appearing as a messy human skin with the cat texture around it, it also had the hitbox of an ocelot/cat. I then tried making another skin on PMC based on a cat by editing a default one and put this as my entity's texture but I kept the same error. What is happening? What have I done incorrectly?
