I can't say I hate cats, but holy cow, dogs are a horse of another color.

You can't cry over spilled milk. ... You need to regroup, and now we'll do what we can in my committee,

Milk the cow that standeth still

Why buy a cow if you can get the milk for free

I don't care how many pails of milk I lose, as long as I don't lose the cow

Never cry over spilt milk, because it may have been poisoned.
