My two hooligans,Jimi (female 1 yr old) and Barkley (male 6 mos old) also like full drinks but for another reason entirely. They love to steal my drinking straws and carry them around like prizes! We find bright colored straws everywhere. They don't even wait for me to sit down to try and heist their favorite palything. Both of them have been known to jump on the counter as soon as I turn my back to put the soda (or whatever) back in the fridge!! Gotta Love Those Cats!
