Hutch is retaining water so badly that she can barely walk under the weight. Does anyone know what would cause this? Her heart and kidneys would be a guess. Could it be her uv bulb? Diet? Inactivity during winter? Depression having siblings die? I dont know what to do. I had blood tests done which turned out quite spendy and I cant get the results till next month when I make the final payment. I hope this is not a serious condition.
