Cool For Cats!

This may set the CAT amongst the pigeons
And also let the CAT, out of the bag
Perhaps creating a CATachresis
Like CATarrh, is a pirate CAT wag

A CATalogue, is a CAT on a log, missed
As a CATalyst, are CATS on a list
A CATechist, meanwhile, is a CAT that likes to be kissed
And a CATholic, a drunken CAT, slightly pissed!

A CATechu, is a CAT with some ills
And a CATerpillar, then taking lots of pills
A CATegory, a cat, hence a dark sense of humour
Finally a CATflap, is an anxious CAT, according to a rumour?
