Cat mass = Buttered toast mass = 6.5kg (balanced crank!) = 64N(ish) force
Torque = F*R = 12.8Nm peak (8ish Nm ave?)
so if they spin at say 12,600rads/sec (= roughly 2000revs/sec =120,000rpm)

Then we get a perpetual engine producing about a 100kW (135hp)!!!
-so it should go like TL

So as long as the butter doesn't fly off the toast, and the cat doesn't explode at 120,000rpm You're set!
