Contraindications:
* If the cats playing with less enthusiasm, you could try the hilly Viriante. Tension can arise because the ball does not simply just rolled, but also makes up and down movements. -> 50735 Catit Senses Tempo - Game rail for cats
* The ball does not roll softly.
* In some balls, it happens that they also light up when they are not nudged and not move. I suspect that the floor is crooked or slightly vibrates through whatever. Thus, the balls are in continuous lighting state and the battery is around 3 months their minds on. -> If the balls are positioned differently, listen to the lights.
* The holes are quite small. -> Toys more suitable for small cats paws.
