How could I forget this one...my cat's idea of a good time is to drop their toys into their water dish or if they have the opportunity...the toilet (how can I expect to train them to do anything if I can't train my husband to shut the lid).
Sometimes they are able to fish the drenched toy out, play continues for a minute and usually the wet toy ends up on the
floor to dry.
The norm usually is wait for mom to fish the drenched mouse (or fuzzy ball) out of the water
