My cat (a doggerel)

[billy]

the skins line messes with the rhyme scheme, i'd go for one more line to make it a 10 liner. no nits other than the above,

my addy would love this. she's a cat person

I hate my cat, my cat hates me.
He purrs at me sarcastically.
He lies in wait behind shut doors
and ambushes with sharpened claws.
He sniffs and sneers at food from tins
then rakes in neighbours' rubbish bins
(he relishes banana skins). if you said skin, or peel it would be a little different from tins/bins as a rhyme and adding a line would sort out the triple rhyme into two two-line rhymes.

Fish-breath cat, I cannot see
why doting pharaohs worshipped thee. Cap P
