As someone else has already mentioned, Cat Laser Light Chasers are great fun!
So are Cat Chasers which you can get from pet stores (or make your own: Feathers/Ribbons tied securely onto a string – cats love chasing them - but you’ll have to do a lot of running around too!)
Organic Catnip tied up in an old sock
More homemade games:
Wriggling your hands under the duvet.
Large empty paper bags.
Crinkled up paper.
Cardboard boxes (when kitten is inside just scratch the outside of the box and he should try to follow the sounds with his paws).
Placing a ruler or pencil through a small gap(bottom of the door works well) and moving it from side to side so that your kitten can see it but can’t see you!
Good luck with your kitten. Great you are looking into a variety of toys and games for him. When Spyro becomes a grown up cat, I’m sure he’ll still really appreciate the games
