cheap toys from home, cat likes the box more

my cat ignore the 400 baht toy I bought at the mall. then she play with the empty toilet paper roll for 2 hours. so now i just make stuff at home lol cardboard box with holes cut in the side, she sleeps and hunts inside. crumpled paper ball is free and she pushes it around the floor all day. old socks knotted together, same thing. egg tray with a few dry kibble inside, she has to flip the cups to find food, slows her down when she eats too fast muffin tray with tennis balls, put it on the floor, she bats them out one by one. careful, remove the tape and any bell, she chews the bell rotate them every 2 days or she gets bored again. that's the trick i think
