I agree with Slick. A full panel blood test would at least tell you if all her organs are functioning properly. My idea from your description is kidney failure, but the symptoms are so similar for other diseases like diabetes. The vet will also be able to tell you if Grasshopper is in any pain and give you a more thorough idea of just what's going on with her. You should be able to get an office visit and blood test for under $150.00. Might seem like a lot, but then at least you'll know what's going on with her and just how much time you might have left with her.

I'm sorry to hear things with your husband have been so rough, but I'm glad to hear things are going better now. And I'm sorry that this has to come up with Grasshopper at such a difficult time for you. The last thing you need now is the stress of having to make such a tough decision.

Good luck and please let us know what you find out.
