Still gutted, so just copying the note we sent to Kelly and Mia...
The sad and inevitable has finally transpired: With a shattered heart I bear news of Matilda's passing.
There was an "episode" in April (mini-stroke?) characterized by general confusion, loss of stability, and an inability to stand / get into the litter box. It was sudden, and we scrambled to get things arranged with the vet for the next day. Just as suddenly, when morning arrived, Matilda had rebounded (almost completely), so we called things off with the vet.
During the past three months, however, we witnessed a slow decline in Matilda's functionality and activity. She stopped coming upstairs, started restricting herself to just the ottoman/futon, and basically just seemed to be winding down.
Probably the final turning point was about three weeks back when Matilda started hunkering on the floor beneath the kitchen table. Once it dawned on us that this was a permanent change, we put towels and pillows (and a cooling pad...been so warm here) down for her and moved the table and chairs out to give her some space.
About that time Matilda also started to go off her kibbles and pâté and would only be interested in cat milk and cooked chicken or canned tuna fish. In the end, she was not even interested in that; she only had one poo in the final three or four days. Bless her little heart: She always made it to the litter tray, even at the end.
The old gal simply ran out of petrol in her tank. Once we noticed that her breathing was sporadically laboured, we called the vet to pop by the house. She agreed immediately that now was time, before any real suffering could set in.
Always gutting to make the decision, even harder to break the news. We are so, so sorry.
