Gimme Gimme Guinea Pigs

From BoardGameGeek:

Gimme Gimme Guinea Pigs is a fast and fun game played in real time! Players start with seven cards in hand while the rest of the cards are spread out, face down, on the table in front of them. Each card has one of six different animals or is a PAWS card. The goal of the game: Be the first to collect all seven cards of one animal and shout "Got 'em!" To start the game one player says "Ready, set, go!" and the game begins! Everyone plays at the same time. Player choose one card from their hand to play face up on the table and then may grab any other card, face up or down, to add to their hand. If a player plays the PAWS card, play stops and everyone passes three of their cards to the player on their right. The PAWS card is removed from the game and the player who used it shouts "GO!" to continue the game. First player to get all seven of one animal and shout "Got 'em!" wins the game.
