What a smart kitty! She hid the collar successfully so you didn't find
it until it was no longer needed. Even the fact that she understood that
she should hide it from you is pretty amazing. Cats in the wild do hide
their kills from other predators, but that doesn't mean they would think
of hiding something from a human that they don't want the human to use on
them. Different motivation.

When we were in a top-floor city flat, one of our cats managed to
biff the "don't do that" water spray bottle off the windowsill
so it landed in an inaccessible courtyard.
