So sorry for your loss, OP...
I lost my beautiful old may to kidney disease at 17 - the vet said he could have months or even years after being diagnosed. But he had exactly five weeks - sudden and severe deterioration with no option but PTS. I held his paw while they did their thing...
I had over £200 worth of prescription food and meds, most unopened, but vet said they couldn't take it back. So I found a local cat charity who were thrilled to get it. They told me the cattery was full to bursting and would I like a cat?
It was much too soon of course! But I agreed to foster a mum cat and her newborn kittens for eight weeks to help them out.
Two years later I am enjoying living with the two of those kittens we adopted 🤗The mum and the others were rehomed by the charity after the eight weeks was up.
It really helped looking after the little mum and the tiny kittens while I was grieving for my old boy. The charity supplied everything, food, litter and kitten formula. They would have found homes for all of them but I fell in love with a ginger boy and a tortie girl.. of course I did, who could resist little furry bundles in need of a home!
Something to think about? All the charities are full and even temporary homes would help them and the cats.
