Have had cats for years, but never came across this before.
We now have a brother and sister, they are about 6 months old. Boy cat, for some reason, loves to drink orange juice - not squash, but real juice. To the extent that today, I left a carton of juice in a bag while I was putting away the rest of the shopping, and he chewed through the bag and the carton, I found him eagerly lapping up the juice as it leaked into the carrier bag. 
He will also jump up onto the table and stick his head into a glass of juice if we don't stop him in time.
They have fresh water all the time, fed properly every day etc etc.
Just wondered if anyone else had a cat with exotic tastes?
