Gosh how cute. Don't forget the indivdual goodie bags!
Hmm fur baby activities, this is going to be worth many pictures, LOL (please share) Maybe games like for instance, play some music and the first fur baby who barks/sings/howls wins a prize.
Or toy races (throw a toy and see who crosses the finish line first), stuff like that? Im not very creative but it sure sounds like it's going to be a blast!!
