When I first got my German Shepherd she always tried to catch Da Bird if it came past her. I taught her to leave it alone because I was afraid she might accidentally grab or run into one of the cats also going for the toy.
My 4 younger cats (1 yr old littermates) will play with Da Bird and compete to catch it except for the chubby one Spot, who usually won't chase it if the other cats are around. My two slightly older (2 year old) cats Church and Roxy will usually NOT chase Da Bird toy if the younger ones are chasing it though, they don't want the competition but if it is just the two 2-year-olds out they will take turns chasing after it. Church jumps the highest, although one of the littermates Blaze is also a really high jumper.
Here is a video of Church leaping after a toy. This was before we got Da Bird and he jumps a LOT higher for Da Bird toy than in this video!http://www.youtube.com/watch?v=0HDTWjdk3HM
