My cat is opaque and has very sharp claws.

A cat without razor sharp claws is but a ghost of what a cat should be.

When cats turn invisible, they lose their claws.

Putting a cats head in a glass box and then in the bin means no more claw marks

The cat destroyed my apartment, my clothes, even my favorite poster; there was nothing left for it but to place his head in a glittering glass case and cheerfully sacrifice it in the pristine tomb in the corner of the bedroom.
