I've noticed over the past week or so, Max is drinking a lot more water. He has never been much of a water drinker (one of the reasons I soak his kibble in water) and he's now drinking his bowl dry at one go, a few times a day. This isn't a steady pattern, he can go most of the day without drinking and then consume a lot. In the overall scheme, I don't think he's drinking an abnormal amount but it is a lot for him (I'm going to start actually mearsuring and keeping track tomorrow). He's peeing what I would say is an equitable amount, with no indication of an inability to hold it, he sleeps through the night.
He isn't different in any other way - still his usual, goofy self! His creatinine has always been a bit on the high side - I believe the last time it was 1.7, never higher. The one thing that is different is I've recently switched foods, to Orijen wild fish formula. This food has no carbs and a high protein value - over 40%. I know for kidney problems a low protein diet is recommended - could a high protein food be stressing his kidneys? Or could it just be making him thirstier? It has been a bit hot the past couple of days, but he was also drinking like this when it was cooler, earlier this week.
I'm going to get an urinanalysis and take him for a check up but just wondered if there were any similar experiences with a high protein food...
