(((( NSRN )))) (((( Spunky ))))
My heart and compassion goes out to you. Spunky is going to tell you when it's time. Since she's doing "well" at the moment, this might just be the rally before the end. I know, that's a harsh thing to have to say, but it may be true.
Please, don't let her continue suffering because of your love for her. You might even tell her just how much you love her, and how special she is to you, but that when it's time for her to go, you'll do what you can to make her passing as easy as possible. Let her know it's ok to leave.
Do have the vet come to your home. When Blackie had to go, we had the vet come in. It was an extra $70.00, but well worth it!
We have a 13 yo diabetic male manx. I'm grateful he doesn't have the nerve problems associated with some manx... He's a stumpy, not a rumpy!. He's also been diabetic for almost 4 years. He gets 2 insulin shots a day. He's very healthy. I took him in a couple months ago cuz he had been loosing weight (he had been overweight but was down to looking good, but we were still concerned) and the vet did a full lab and exam, and he's been deemed very healthy for a 13 yo cat, and extremely healthy for a 4yr diabetic. I'm pleased because it means we're caring for him well.
