We just came back from the vet's appointment about an hour ago. We are still none the wiser.
It wasn't our usual vet, but the other one. He also had dealings with Lucy when she was very ill 14 months ago and remembered her. He is puzzled too. Her heart and lungs are absolutely fine, she isn't running a temperature, her motor responses are back to normal - she just won't eat or drink (at least we haven't seen her eating or drinking). The vet said she is not dehydrated. Basically, we've been told to just keep observing her over the next couple of days and if she is no better by Friday, or if she deteriorates, then they'll see us as an emergency case. Huw (the vet) didn't really want to take blood tests at this stage (I might be reading more into it, but could this be because he knows she's reached the end of her life and she knows it, and to take blood tests would distress her?) and he was sure it is not kidney or liver failure.
When we were at the vets, she was sitting up in her basket, looking around her with interest. She's still as sharp as a button - yet it just seems she's forgotten how to eat and drink.
Has anyone seen anything like this before? I'm at a loss as to what to do now. It's almost like she's just starting to fade away. Today I had to fish her out from under the middle of our bed - the most inaccessible part of it. When we came back from the vets, she said "hello" to Snowy then promptly disappeared back under the bed again.
I really don't know what to think and I'm at a loss as to what to do for the best.
