When Mars, the planet and ancient god of war and battle clashes with Pluto, the god of the Underworld, irritation is the least you can expect. It could be fully blown war, it could be irritated words in fighting, it can come out as brooding and sulking. It also gives you a big boost of energy, so you can get things done.
Cheetah is one of the cat family, mysterious and appealing at the same time. Cheetahs are known to be the fastest runners, so use your powers to outrun what either threatens or challenges you to fight to keep peace.
In every case, the message is: approach with caution. Would you like to poke the cheetah above who’s obviously irritated. That’s a good image to keep in mind when this aspect is active in your own chart or in the skies.
