'Jack' the Pathological Feral Cat

Here is one of my most interesting pathological skulls! I didn't notice anything unusual about him when i skinned him, or even when i was processing the skull (i guess i never really stopped to look too closely) but when i was washing a batch of skulls after processing, he suddenly stood out! I'm not sure what caused the bone growth around his eye, possibly an infection or injury
I decided to keep him for part of my collection! 

I have uploaded a couple more quick snaps of him here- sta.sh/2224r1q76cmf
