Use the right arrow key to move. (You can walk backwards but not move areas backwards.) Click on a cat when you see it to catch it. Some cats require a gift in exchange for their capture, find the food they desire to make them happy for you to catch them. If you end up going round again, don't catch the cats again, just the ones you know you missed. Challenge: Once you complete the game once, why not try holding down the right arrow key and don't stop while trying to collect all the cats! Give it a go!
This is a remix of Kitty Hunt By Cheesepuff3. Please note: I have never completed the challenge but I do know that something AWESOME happens when you complete it.
