For what it’s worth to you, we took the body of our 21-year-old cat home from the vet after euthanasia, washed him and combed his fur, and laid him out in our house overnight. The next morning, rigor mortis had not yet set in, and we petted him some more, wrapped him in a cloth and placed him in a box, and drove him personally to the crematorium. We will scatter his ashes on the family plot. He was a member of the family. So was that precious little child who died in their arms.
I’m glad for you and your cat but the question was, do hospitals even allow that now?
