Our family's favorite game! The Monster Monster Game - Actually for this game, it could be "Puppy Dog, Puppy Dog, are you hungry?"
Go on a Hunt. Send your guests on a hunt around the yard to look for toy stuffed animal kitties! Plan your hunt.
Cat and Mouse Game - Form a circle with everyone holding hands. Have one person be the mouse (who will be inside the circle) and one player be the cat (who is outside the circle). The cat then tries to catch the mouse. The players making the circle can let the mouse in and out of the circle to try to avoid the cat. If the mouse is caught, they become the cat and a new mouse is chosen.
Ruff! You may even want to team kitty party ideas with a dog party for even more birthday party fun!
Party Favors can be as simple as a stuffed animal cat. I've given these at parties and found my best deal on Ebay. I've even found Ty Beanie Baby Cats for as low as $1 a piece! Keep your eyes open and check frequently for good deals.
