Cats in Time

Hello explorers! My name is Professor Tim Edger, and I'm the inventor of the time machine and an avid cat lover! Sadly, I have a problem, and maybe YOU can help me. You see, my beloved cats are missing. While playing in the lab, they've activated my time machine and ZAP, now they are lost in space and time! You have to travel from ancient Egypt, all the way to the streets of late 20. century New York, and even beyond the present - to future Tokyo. Your goal is to find all the cats! Please be careful; these cats are really good at hiding.
