I put mine up high. Maybe I should experiment.
Tam's favorite toys are pompoms and twist-ties. Halvah...thinks she's too dignified for such things, most of the time.
Of course, when she DOES play, she's rather like a stampeding elephant, and tends to take out small furniture. So maybe she shouldn't be encouraged.
A twistties! Alpha loves those too. Beta mostly loves sleeping and eating but is up for a bout of play now and again.
