twist ties that they just push around and chase
ribbons which they wrestle with (although this is not recommended because they could eat it and it could get tangled up in their stomach) - I did give ribbons to them in ball form to push around with a tail dangling.
boxes when they can hide OR be pushed around in
trash cans and other containers that they can dig through (especially if it only has paper)
paper clips, hair clips
covers of drains
When I got the two dogs, I went on my little shopping spree again but I learned from the two cats and did not buy as much. Good thing because they fell in love with other things:
plastic ball of the cats - with the bell inside it
empty toilet paper and paper towel rolls
old leggings and pillow cases tied up in knots for tug of war
yarn tied up in knots to chew on
What amazes me is the creativity that comes out of them when they decide they like something. Bimbim would ask us to tap the bottom of the trash can and she would push it around chasing our feet. You cannot imagine how many bruises I got on my shin whenever we played this game. Sumo had me on my hands and knees pushing a box he was riding in. He in turn chased things through the holes in the box as it moved. Sumo learned to open doors when hunting for his balled up ribbons. Since I was not home much when Charis was young she learned to entertain herself by tossing around her favorite toy Blue around.
Of course my personal stuff is free game for them. Keegan fell in love with my cell phone case which he chewed even if the cell phone was inside. Bimbim considered certain trash cans hers, if I threw paper in it or anything else it would end up on the floor when she sees it. Keegan tried to lay claim to my crocs sandals too.
Let them have their fun at home, let them choose their toys and be amazed at their creativity.
