I'm going to extend the number of cats to 30 as this is so popular! Congratulations to a new reader- RubyGaming05 - for guessing Feathertail as the last cat!

Thorns around me,
Cold inside,
My love for her,
I couldn't hide,
A vicious fighter,
Swift and strong,
Blood ran around me,
All day long.
I met my end,
Another way,
Bloodthirsty torture,
Was my say.
