What causes a high protein count in cats?

Question

My soon to be 5 month old Kitten, Mushy, isn't doing so well. He's somewhat dehydrated, and we have to keep putting him up to the food to get him to eat, but otherwise he just sleeps. Patch (sister) our other kitten, was the same way and she was diagnosed with 'wet' FIP and didn't make it. Patch was said to have had a high protein level count before she got drastically sick with FIP. Mushy today was diagnosed with having a high protein level count as well. My question is, what causes a high protein level count in cats? All I keep coming up with on my own is that it's a symtom of FIP, but surely there must be something else and the vets are saying that maybe it's an early stage for FIP. He doesn't have any fluids building up in his lungs/abdomen at the moment, so we're hoping that he has something else. Last week Sebastian and Mushy (brothers) were said to have had a 'cold'. Sebastian bounced back rather quickly, but Mushy hasn't. Again, other than being a symtom of FIP, what causes a high protein count in cats? Thank You.

Answer 1

Kidney issues can cause a high protein count also.  The problem with FIP is that it has the same symptoms of many other things - it's a diagnosis by exclusion of all of those other things.  

Have they been tested for FeLV?  

Answer 2

The high protien is a symptom of something else. Try some gerber Ham baby food. The meat flavors work well for our cats when they are sick. I pray it is not FIP  

Answer 3

High total protein is a very vauge sign and can be due to dehydration or inflammation.
