These are just a few of the uses I have found. I would appreciate any
ideas anyone can add.

We no longer have a pet rabbit, but filling them with water and
freezing them makes a great way for a rabbit to cool off on a very hot
day. They stretch out beside them for a nap...

Punch a few small holes on the sides, cut the top off and sink them
into your pumpkin or melon hills as a great way to get water to the
root systems.
