Is it a sonnet?

This poem is written in the sonnet form
And yet I have my doubts about its shape
Though nearly to that structure it conforms
There may be places where non- essence gapes.

It looks and speaks just as a sonnet would
And talks of metaphysical concerns.
Do we conclude, as poets and writers should,
That in our schizoid age we cannot learn?

For humans may be clothed in skin of wolves;
And lambs be decked with lions’ fearsome furs..
Thus senses can be tricked and problems solved.
Which of us will praise a cat  that purrs?

It looks like one,it feels like one,it speaks.
Yet  nothing human’s heard except our shrieks
