We have been very strict about Fister's Precription diet the last 3 days (low magnesium, phosfor and calcium) and we have put water in front of him whereever he was sitting - luckily he was drinking some and today he is more or less back to normal it seems. Has been to the litterbox 3 times since yesterday afternoon with good results.

A couple of times I've tried to fill a syringe (get it at the chemist) with water and sprayed it in his mouth - amazingly enough he accepted it. Ok, it's only a little at a time, but worth a try if he won't drink.

Does anyone know if there are much magnesium, calcium or phosfor in liver, white fish or red meat?
