DIY toys for cats who get bored, cheap

Thor is so bored at home when I go to class. Me and my mom dont have much money so I made toys from things at home. Here is some: Toilet paper roll with a treat inside, he push it around for 20 mins. Cardboard box with holes cut for the paw. Old sock with a bell sewed in, he chase it all over the flat. Fon, our big Maine Coon, she not play with any of it. She just sit on the box and look at us. Lol. Plastic bottle with dry rice inside, make noise, Thor like that more than the cat toy from 7-Eleven. Please careful not to let them eat the string, very dangerous. Take the string away after play. Anyway good luck making your own toys.
