Thank you for the lovely comments on my last entry. Sadly, things moved fast and Cassie continued to deteriorate and not eat over the weekend. She spent quite a bit of time curled up in my lap, sleeping and having strokes, which was good, but she was obviously in a very bad way. We took her into the vet on Monday, who told us that her kidneys were shutting down. They took her to cat hospital and put her on fluids to see how much remaining kidney function there was but when we checked in the next day, her blood work hadn't improved at all, meaning that her kidneys were basically completely non functional. There was nothing that they could really do for her so I went after school and sat with her for an hour or so giving her strokes and fuss before the vet put her on my lap and gave her an overdose of anaesthetic.
It's the first time that I've lost a pet in that way - we had goldfish, who used to get regularly pinched by herons, but that's nothing like the same. I cried a lot on Monday and Tuesday and was pretty fragile most of Wednesday and the rest of the week. Now I just get ambushed by odd rushes of sadness. Charlie has been doing her best to look after us by coming and sitting with me on the sofa and so on but I miss Cassie very much.
I have quite a few versions of this pic where she's sitting on my lap giving me a very definite *look*
And quite a few where she's curled up on the bed. My photo albums all together seem to suggest she spent quite a lot of time chilling out and relaxing, which is a good thought.
