Impressive domestic cat skull
#1
There are probably bigger cat skulls out there, like full blooded maine coons, but I have yet to see one with such a large sagital and nuchal crest in proportion to the rest of its skull. The skull belonged to an 18/19 pound feral cat that wasn't fat.

What is a sagittal crest?

A sagittal crest is a midline ridge on the skull of some mammals. It is used as an insertion surface for powerful chewing muscles.

Same domestic cat skull compared to an adult female bobcat.

In my family, we have kept a number of quite sizeable domestic cats ( in the 7-10kg range),
& while neutered males can grow quite large, the biggest skull def' belonged to our intact-tom Manx.

He had such a pleasant nature/chilled personality, that he didn't get the 'unkindest cut' & so developed the
testosterone-boosted massive head, neck & shoulder musculature typical of the tomcat, but due to his almost
rabbit-like large hindquarters proportions & big back legs, so he kept his balanced cat-look much better than
domestic tomcats usually do.

He was a 1/2 tail Manx we saved from a breeder outfit, (since they only wanted no-tails), but we often
were asked by visitors - 'Wow, is he a real bobcat' &, 'What happened to the other 1/2 of his tail?

Tomcats also typically develop a thick skin-padding 'armour' on their facial areas to resist clawing damage
from other cats over regular territorial disputes.

Our Manx sported a pale 'Champagne' tawny coloured spotty-tabby upper coat over the white under-sides of
his medium-length pelage, (which did indeed make him look bobcat-like) & he also certainly had a big jaw,
with substantial teeth, so he'd happily crack 'n' crunch through turkey leg bones, to get to the marrow.

Yes, on the weekend, I took the opportunity to 'massage' ( he didn't object, at all) large, but older ( in his mid-teens) neutered male domestic, who now shows a typical age-related loss of muscle mass ( he's still ~7kg, but not fat).

He'd been a very active, well-developed, athletic hunter of a cat, when in his prime, but is now quite rangy/bony.

Those muscle-insertion ridges on his skull, shoulder-blades & other prominent bones, are certainly quite evident to the firm touch, under his reduced musculature, & loose fur coat.
