They love ice cubes and have a "time" with it... specially on hot summer days... another good thing about it is to use as a "tool" if they need to take extra liquids , when they get dehydrated or "post op" care, or when pancreatites happen and they need "pedialyte" for examples , just freeze in an ice tray and give one at a time... it is usefull both ways: to keep an ongoing injestion of liquids and to keep them to injest too much liquids at once since they "take theyr time" to lick it !!!! Hope you like the tip....
