Gosh, it varies. Jack sometimes gets 2 20 minute or so play sessions with his favorite wand toy. This involves 4 different rooms of my home which have cat trees of differing heights.I run through all the rooms taking him up and down the trees, across the sofa's and into a room in which I have cat climbing shelves that lead up and down a wall of bookshelves. He then likes to have me flick the toy into his tunnel which he runs into and shoots out of like a bullet. When I play this particular toy Farrah and Milo do not compete for play because Jack will not share
If I am tired I use the laser because he doesn't go nuts and Farrah can play too ( Milo does not fall for the laser) Same routine, all over the house and up and down the wall, tunnel etc. Later , if I use the wand toy that has a long multi colored felt tail , Farrah goes nuts , but she never goes so nuts that Jack can't join in.
Milo, is craftier, he doesn't want to leap or jump around. He likes the wand toy with the mouse ( GoGo Dancer?) he likes to strategize, hiding behind various pieces of furniture and leaping on the mouse, shewing on it a little before hiding behind a different piece of furniture to repeat the process. At the end of this he tends to flop on his back and grab the toy and madly swat it. 10-15 minutes seems to be enough for him.
When the weather is nice I play in the backyard with him ( cat fencing ) and he hides behind a tree and I have to run by and pretend I don't see him ...Sometimes I get da Bird and play out there with all three. Jack tends to dominate. So, I geuss I end up playing with them 4-5 days a week for a total of 1- 1/2 hours . Some days just 1 15 minute play session each. I work in a home office so there are times the phone rings and play comes to an abrupt end.
