In this case it was a 16 YO cat the SCSon named "Lear".
She had always been somewhat sickly. Shortly after adoption she needed some serious intervention to cure "intestinal bugs". We got her as a rescue and I'd like to think we gave her a good home for the past 16 yrs. More recently the SCQueen secured special dietary feed and the cat had lost a lot of weight. She was pretty much skin & bones :-(
Now that Arizona is in our cold season, She spent her time in the "Warm Spots" she found in the house. Some times that was following sunbeams through the South facing windows, but also the corner of he refrigerator where heat is exhausted.
Lately she had pretty much lost control of her bowels, leaving calling cards all over the house. Fortunately most of the Sand Castle is tiled so cleanup is relatively easy compared to other flooring systems, even if messy and inconvenient.
Today she succumbed to her ails at home, in comfort and accompanied by the SCSon.
Still sucks to lose a pet.
