Put a Sock in It!
Yes, this trick works. For a while, anyway. Then she’s on to the next toy.

Water Bottle Sock Puppet
Supplies: Orphan sock, used plastic bottle (no cap!), smelly treats
Tools: Scissors (optional)
1. Cram treats into water bottle.
2. Place water bottle with treats inside sock.
3. Make a very sturdy knot at cap end (using the scissors if need be to cut strips for a tighter knot).

Note: Once the sock gets slobbery, the bottle loses its crinkle and the treats get as stale as the last couple of seasons of Friends, you can always swap them out for fresher recyclable fare.
Variation: As with the tennis ball, you can wrap a larger bottle stuffed with smelly treats (I used dried Icelandic catfish skins!) in a denim pant leg. That one went over really well, too.
