Lorie D. you had me in tears! LOL!!!!!
I'm really surprised that this one hasn't shown up yet: the plastic ring that some bottles have as a safety measure holding the top on. We get them mostly from orange juice tops. You pull up on the tab, so when it's off the ring it isn't an unbroken circle. But they love flipping it, picking it up with their paws, gripping it with their toes....
Shelly's a shredder too.
Lazlo loves the little mice, but only if they're furry on the outside and have something inside that rattles a bit.
The plastic safety rings that come off of cottage cheese, sour cream, etc. can be entertaining for hours.
Brown paper bags are probably close to Shelly's favorite thing. Hiding in them, pouncing on them, chewing them, shredding them, (preferably if Lazlo's in it), hiding toys in them and tearing it apart to get at the toy (usually the orange bottle ring! :tounge2: )
Boxes are almost as good as plastic bags. We make mazes out of boxes (cutting holes and taping them together, 3D too!) for them and toss toys they want in there.
Elastic. It has to be kind of thick and pretty stiff with a knot in the end of it. Or tied into a loop.
You know the little plastic tube that the teeny M&Ms come in? Stick anything in there that rattles (if the M&M have been eaten!) and it is the game of choice.
...they used to love the plastic ring with the ball that goes around and around....but the get tired of the fact that they can't catch the ball and pull it out. Stick ANYTHING in there that moves around and that they can get out with a little effort, and they're happy cats.
Flies. Although be careful, that can create real damage.
Spiders are usually frustrating - as they're most often on the ceiling. "mmrrrrrooooow!" "look mom - look up there!"
Bird watching. It's not a toy, but it is definitely a favorite past-time. Although falling leaves, bugs flying by - all are just as interesting.
