How to play Cat Trick

About Cat Trick, from BoardGameGeek:

Kittens are obsessed with their toys! They're on a mission to collect as many different ones as possible. But watch out: if players get too greedy and keep collecting the same toy over and over, they'll crash-and the others will pounce on their toys. Who has the cunning of a cat and knows when to hold back? Play any card-no need to follow suit. Play the highest card or a trump to win the trick. Collect 5 different colors-but don't take more than 4 of any one! -description from the publisher
