Miawwwwwwww really nice photo you have i love cat. anyway let's go to the critiques. i love the vision about ow you put the cat on left position but still left the object a "breathing room" in rule of third. it's nice.
it's a lens cap ? LoL yes it's not a mouse anyway if i was you maybe i will use a Computer Mouse instead of lens cap. why ? it will look more funny and more suitable with the title.
Originalty well it's a cat right and also the technique i am not underestimate you but usually most people who have advance knowledge at photography are know how to get image like this. i mean Open Aperture with pretty fast Shutter speed to freeze the object.
but the kitty are so cute so i give it high impact anyway try something more challenging like playing with composition and angle
anyway sorry for my bad english and have a nice day
