If you move the toy toward the cat you will cause confusion because no prey in its right mind would willingly race up to a predator. When movements go toward the cat it can change the tone of the game from predator and prey to two opponents. That certainly won’t be fun for kitty. He’ll switch from play-mode to defense-mode and that’s not the effect anyone wants.
Vary Speed of the Cat’s Toy
If you want this to be a fun and rewarding game for the cat, alternate fast and slow movements. In a natural hunting setting, the cat would use the times that the prey has momentarily stopped moving to advance his position silently. If the prey is in constant motion it becomes more dumb luck and less predatory skill for the cat to accurately stalk, pounce and capture. The times that the prey isn’t moving are the times when kitty is planning his next move.
Highs and Lows
If you’re using a bird-type interactive toy don’t keep the toy flying through the air all the time. Alternate some ground movement. It’s the time that a bird is on the ground feeding that the cat would have a better chance for a capture.
