I'm sooo thirsty

Isn't it always the way. We put water down for the cat to drink, however there must be something wrong with it, Sheba will either drink from the scummy pond, the dew from the grass, rainwater from the lid of the peg bin, or as seen here the watering can. The contortions Sheba has to get into to get her head into the narrow opening. It must taste pretty good.
