There are a lot of different things that appear when you search for "cat wand toy", but IMHO, I (Dee) believe that cat wands MUST always have a string or strip of fabric, and some kind of lure at the end of the string, something the cat can focus on as an object to attack.
Use catnip wisely. Catnip is a useful tool for getting your cat to exercise, but Hofve says it’s best to use it only in the proper situations. “Remember that not all cats respond to catnip, and of those that do, a few will become aggressive from catnip,” she says. “Also, never give catnip before a stressful event, such as a trip to the vet. Your vet will thank you!”
Create a "hockey rink". Put a ball in a large cardboard box or the bathtub. As the ball goes flying off the walls (and the cat goes flying after it), you’ll get some laughs and your cat will get some much-needed exercise. (I would probably buy something like this to form the "rink")
Go outside. (Pelé had previously had lots of access to the outdoors, but she rarely took advantage of it, so I doubt she'd be willing to now)
Create an agility course. You might be more familiar with these challenges for dogs or horses, but cats can also enjoy this mix of speed and challenge. These programs include a number of obstacles, such as bars to jump over or tunnels to pass through, which push your cat both physically and mentally. Hofve recommends researching cat agility courses online.
