Accidental Leakage in the Night

Now from the title you may have the wrong impression, after successfully requesting to be out at 5:15am I came back to bed with a rubber chew toy. However after settling back in my basket to go to sleep instead of chewing the toy I started to rip the neck out of my hot water bottle, which had been provided for my extra comfort. Soon after ripping a hole in the water bottle it was brought to my attention that jumping on the bottle, produced a very entertaining fountain of water which I proceed to chase and try to eat.
Unfortunately this excitement resulted in me having a very early morning due to wet dog, wet blanket and wet bed.

Morning :)



Who did that?
