The only time I ever saw Lily drink from a leaf was the day I brought her home! She did learn to drink from a syringe (no needle) and would usually have a drink near to lights out time. I was always worried that she didn't drink enough and she more often than not had a slight orange tip to her urates, but she did only empty her bowels once a sweek or so. I just figured that the longer the urates are in the body, the more dehydrated and orange looking they become. At her post mortem I asked the vet about her kidneys and he said that they looked ok, and this put my mind at rest, so she must have been a secret drinker.
They do lick their lips when misted and drink a small amount this way. Also I was told that they can absorb moisture from the humidity in the enclosure. I have got Amy to take water from a syringe too but she'll only drink when she wants to!
Tommy, on the other hand, needs a bit of encouragement! He had a sripper and a (nasty) bowl of water that he drank from. He wasn't misted that often before I got him - he just had water flicked at him, so he is getting used to being misted and he does lick his lips. I did get him to drink almost a whole syringe full when I first got him home and put him in his cage as he was very thirsty after his journey. He produced a rather orange urate and very moist poop this morning. I am reserving judgement until he is settled and produces another for me to inspect! I am trying to get him to drink at every opportunity. Having said that his eyes are very full looking and he doesn't look dehydrated at all so I am putting this one down to the stress of being relocated.
Thanks for the post
