IRN tetherball & soccer?

[fiona]

So Fiona hates her cat balls (have bells in them), But she love to hate them. We have Made a little tetherball thing for her to play with and she love it! We also play soccer. I roll the ball to her and she'll chase after it and toss it back. I have to roll it pretty fast to get her to miss it lol. How funny would it be to have a mini soccer field with her playing on it. I mean she literally dives for the balls.
Someone told me it is bad to let her be aggressive to her balls because she will be aggressive to us and she stopped giving her IRN balls because she would bite her if she tried to take them. Sometimes she will charge me if I'm going after a ball, but I give her the evil eye and tell her to chill out and that usually works, she just gets really into the game. She really seem to enjoy it though and gets LOTS of exercise, so what do you guys think... good or bad?

Fiona I think it's great that she is interacting with you. Keep the games going, sounds like your both having fun and that's what it's all about.
