A Question of Decorum

When your cat dies, how long do you have to wait until you purchase a new one? Is it wrong to get a new one that very night?

If not, why doesn't someone open up a drive-thru kind of Store-etary where you fling your deceased cat's carcass into the first window (The Incinerator Room), drive up to a cat menu to find the replacement, and make the purchase at the third window?

(Note: This won't work for dogs. They have souls.)

If anyone can put a business plan together for this idea, please contact me. I have hundreds of nickels I'm looking to invest.
