Does anyone else have a cat that does this? I noticed him doing it during the night with my drink on my bedside table (apple and pear robinsons) but now he tries to do it any time with most drinks if I have them in a glass! I have resorted to drinking out of water bottles as I am sure its not good for him to drink these things.
He has also suffered before with crystals in his bladder and and now has specialist food to try and prevent it from happening again.
Just wondered if any of your cats have similar habits?!
