Thank you Dr Bruce. I won't give him any more water for 8 hours. He hasn't eaten anything anyway for the past 48 so keeping food from him will not present a problem. I have just heard that cats can die if they don't have water over a 24 hour period and I was anxious about that which is why I kept giving him about 2.5 to 3 mls of water every couple of hours or so. I will monitor him and see how he feels and if he's not improving then I will call the vet. As far as I am aware, he is not in pain I have felt his abdomen but he didn't show any discomfort. Thank you again.
