Its a Zoo Out there

Smell a Rat – fell that something is wrong

Go to the dogs – become run-down

Fishy – strange and suspicious

Take the bull by the horns – take decisive in a difficult situation

Horse of a different color – quite a different matter

Let the cat out of the bag – inform beforehand

For the birds – uninteresting and meaningless

Straight from the horses mouth – from a reliable source

Horse around – play around

Cat got your tongue? – cant talk?
