It's Symbio-tic

Scratchy:
I don't know why I trust him
I guess some cats just never learn
Itchy:
I feel so good when I have crushed him
Or left him mangled, maimed, and burned
Both:
I supposed it's symbiotic
And perhaps a bit erotic
Scratchy:
'Cause pain is my narcotic
Itchy:
You really liked it?
Scratchy:
Yes, I loved it
Both:
And that's why we're always...
Itchy:
Fighting
Scratchy:
and Biting
Itchy:
And dynamite igniting!
