Not sure what got me thinking about this but... We have 3 cats but one in particular who loves to "help" while I am maintaining my 29 gallon aquarium. He sits on a chair or follows me back and forth when I am emptying/filling buckets, basically watches my every move. So I take off the light and the hood and putting it aside, I swear my back was turned for 5 seconds tops before I am turning back to start taking décor out when I discover I have to take a cat out first, his entire front half, except his head was in the water. Fortunately there were only a couple fish in there at the time. So I get him out and somewhat dried off, make sure fish are ok and figure, great disaster out of the way now should be smooth sailing from then on. Yeah right.... so now I have taken out all of the décor and am vacuuming the substrate, cat then decides old fish poopie aquarium water tastes way better than the RO stuff that is in his waterer. Keeps trying to drink out of the bucket so I have the vacuum in one hand and am trying to use the other plus feet to fend off the cat so he doesn't dump the bucket over. He finally gives up and wanders off... or so I thought & exactly what he wanted me to think... I resume vacuuming and think wow he is being so good finally, and I can just relax and enjoy taking care of my tank. After a few moments of bliss I realize my foot is getting soaked, I look down to see that he's snuck back, has pulled the hose out of the bucket, it's pointed at my foot spewing water and he was happily chewing on it (the hose not my foot ).
