"Cash cow" I've seen a dairy cow and a beef cow and even an English cow can't say I could tell the difference, does a cash cow blend in too? It would be nice to have one I think.
I think the proper term for it is Wagyu, which means, Japanese cow. Here's a link to a Wagyu rib roast that costs $1,400. The most expensive Wagyu is Kobe beef.

A dairy cow needs to be continually impregnated to produce milk. A cash cow can be milked for a steady revenue stream without much investment or effort at all.
