Facts On Cat

Hey guys,
heres a meteaphor I found in the poem Cat.

"Kin lean and slim"

I think that the poet is trying to say that the cat (or cat's) is very poor and is starving.
I also found out that there was less than 7 words in every line.
Some alliteration was: "Where woods"(line 21), "Deep in den"(line 10)
I think that the poet was showing where cats come from and that not all cats are nice and cute.
