I think I have invented history’s greatest most profitable, most unethical business plan:

Step 1. Buy a chunk of radioactive material. Spread it around a room.

Step 2. Start breeding kittens in that room.

Step 3. Kill the ugly deformed offspring, and maybe the normal ones too.

Step 4. Collect the ones with cute mutations (2 tails, 4 ears, etc.) and sell them on eBay!

I hereby claim ownership of this business plan, hence anyone who tries it will have to cough up royalties, payable in savage beatings.
